Abstract:

Bio-diesel was synthesized by hydrogenating the non-polar fraction of the bio-oil produced from the co-pyrolysis between corncobs and polypropylene. Co-pyrolysis of corn cobs and polypropylene was conducted in a stirred tank reactor at heating rate of 5°C/min and maximum temperature of 500°C to attain synergetic effect in non-polar fraction yield where polypropylene served as a hydrogen donor and oxygen sequester so that the oxygenate content in the biofuel product reduced. Stirred tank reactor configuration allowed phase separation between non-polar and polar (oxygenate) compounds in the bio-

Abstract:

A series of low-loaded metallic-activated carbon catalysts were evaluated during the selective hydrogenation of a medium-chain alkyne under mild conditions. The catalysts and support were characterized by ICP, hydrogen chemisorption, Raman spectroscopy, temperature-programmed desorption (TPD), temperature-programmed reduction (TPR), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR micro-ATR), transmission electronic microscopy (TEM), and X-ray photoelectronic spectroscopy (XPS). When studying the effect of the metallic phase, the catalysts were active and selective to the

Abstract:

The semi-hydrogenation reaction of alkynes is important in the fine chemicals and pharmaceutical industries, and it is thus important to find catalytic processes that will drive the reaction efficiently and at a low cost. The real challenge is to drive the alkyne-to-alkene reaction while avoiding over-hydrogenation to the saturated alkane moiety. The problem is more difficult when dealing with aromatic substitution at the alkyne center. Simple photocatalysts based on Palladium tend to proceed to the alkane, and stopping at the alkene with good selectivity requires very precise timing with basi

Competitive hydrogenation of alkenes (cyclohexene, hex-1-ene, hept-1-ene, oct-1-ene) and dienes (octa-1,7-diene, cyclohexa-1,3-diene) was carried out by catalytic hydrogen transfer from ammonium formate on palladium in methanol. The adsorptivity and reactivity of the hydrocarbons decreased in the series: cyclic diene > linear diene > linear 1-alkene > cyclic alkene.

Research has been carried out on the cracking mechanism of 1-octadecanol into short chain alkane and alkene compounds using a cracking technique using a Fluid Fixed Bed reactor, which is operated at temperatures between 450 oC to 500 oC for 30 minutes. The catalyst is positioned so that the feed vapor passes through a number of catalysts. The resulting product was analyzed using GC-MS. The results obtained are as follows. With the Ni/ZSiA catalyst, the catalytic hydrogenation of 1-octadecanol to 1-octadecene reached 20.21 percent, 5-octadecene reached 14.37 percent, and 9-octadecene reached 10

Abstract:

The combination of intermolecular enyne cross metathesis and subsequent 1,4-hydrogenation opens a stereocontrolled and atom-economic access to trisubstituted olefins. By investigating different combinations of functionalized alkyne and alkene substrates, we found that the outcome (yield, E/Z ratio) of the Grubbs II-catalyzed enyne cross-metathesis step depends on the substrate’s structure, the amount of the alkene (used in excess), and the (optional) presence of ethylene. In any case, the 1,4-hydrogenation, catalyzed by 1,2-dimethoxybenzene-Cr(CO)3, proceeds stereospecifically to yield exclus

Abstract:

This chapter begins with a discussion on the functional groups of alkenes and alkynes: carbon-carbon double and triple bonds. It highlights that the simplest alkene is ethene (ethylene) which acts as a plant hormone controlling the maturation of flowers and fruit. The chapter then reviews the regioselectivity and stereochemistry of electrophilic addition to alkenes. It argues that the characteristic reactions of alkenes and alkynes are addition reactions which may be initiated in various ways depending on the nature of the alkene (or alkyne) and the reagent. The chapter then presents the most

Abstract:

This chapter focuses on the differences between alkynes and alkenes, particularly those that affect synthetic work. It explains that one difference concerns the CC double bond, which is usually created from saturated intermediates by elimination but is formed in a different way in alkynes. In these, ethene is widely used in building up the higher members and other compounds containing the triple bond. The chapter observes that alkynes are less reactive than alkenes, but with nucleophiles, the relative reactivity is reversed as simple alkenes do not undergo nucleophilic addition while simple al

Abstract:

This chapter addresses the reduction of carbon–carbon double and triple bonds. In particular, it examines ways of reducing multiple (π) bonds between carbon atoms by the addition of hydrogen (a process known as hydrogenation). The chapter begins by looking at the reduction of alkenes. Reaction of an alkene with hydrogen gas and one of the transition metal catalysts results in the reduction of the π-bond and formation of an alkene. The mechanism by which heterogeneous hydrogenation proceeds is complex and difficult to study as the reaction takes place on the surface of the metal, and the nature

These are the reactions that characterise the chemistry of organometallic complexes, and this is the reason why organometallic complexes are used as catalysts for a variety of synthetic organic reactions.

Abstract:

This chapter assesses reduction. The two most commonly encountered types of reductions in stereoselective organic synthesis are the reduction of alkenes and the reduction of carbonyl groups. Usually, these are very different types of reaction (although occasionally the same reagent will do both), and each encompasses a very large area of chemistry. The chapter considers some of the more important aspects of these reactions from the point of view of stereoselective synthesis, along with a few examples of their application in organic synthesis. It then looks at the reduction of C–C double bonds
