Abstract:
Hydrazine reacts with phthalic anhydride to give a mixture of cyclic hydrazide and N-aminophthalimide. However, the N-aminoimide is exclusively formed in high yield by the reaction of 1,8-naphthalic anhydride with hydrazine. N-aminoimides act as amines and react further with cyclic anhydrides to yield stable bisimides containing an N-N linkage. The syntheses of several bis(N-aminoimide)s from the corresponding bisanhydrides which contain the naphthalic anhydride moiety have been described. Novel high molecular weight polyimides have been synthesized by the reaction of these bis(N-aminoimide)s

Abstract:
Over the past recent years, β-aminocarbonyls have been of great interest to medicinal chemists. As a practical method to obtain these moieties, alkene aminocarbonylation, accounting for the formation of a C-N and a C-C bond, has been the subject of limited research efforts (very specific intramolecular metal-catalyzed variants have been reported). Direct aminocarbonylation of alkenes constitutes a challenging and an important potential innovation in the synthesis of β-aminocarbonyls such as β-amino acids. The research efforts described in the present thesis have been primarily directed towards

Carbamoyl azides could be synthesized in high yields from both aryl and alkyl amines. The carbamoyl azide reaction was found to be much more efficient with Cs (+1) present.

Shilabin Department of Chemistry, East Tennessee State University, Johnson City, TN 37614, USA ABSTRACT Pyrrolo [2,1-c] [1,4] benzodiazepine (PBD) is a class of natural products obtained from various actinomycetes which have both anti-tumor and antibiotic activities. They can bind to specific sequences of DNA that can trigger a biological response which is of pharmacological interest. PBD can also prevent cell division leading to death of the bacteria. This

Abstract:
This Thesis describes the synthesis and reactivity of titanium-nitrogen multiply bonded compounds. Mechanistic and bonding studies on titanium imido, hydrazido and borylimido complexes as well as on a novel scandium borylimide recently reported in our research group were described. <b>Chapter 1</b> provides an introduction to Group 4 and Group 3 metal-nitrogen multiply bonded compounds including synthesis, bonding and reactivity of titanium imido, hydrazido, alkylidene hydrazido and borylimido complexes, (L)Ti=NR, (L)Ti=NNR<sub>2</sub>, (L)Ti=NNCR<sub>2</sub> and (L)Ti=NBR<sub>2</sub>. <b>Chap

Abstract:
A combined experimental and computational study on the reversible ortho-metalation exhibited by the triosmium cluster Os3(CO)10(dppm) (dppm = 1,1-bis(diphenylphosphino)methane is reported. The conversion of nonacarbonyl cluster HOs3(CO)9[&#61549;-PhP(C6H4)CH2PPh2] to Os3(CO)10(dppm) is independent of added CO and exhibits a significant inverse equilibrium isotope effect (EIE). Reductive coupling of the C-H bond in HOs3(CO)9[&#61549;-PhP(C6H4)CH2PPh2] leads to the formation of agostic C-H and two distinct aryl-&#960; species prior to the rate-limiting formation of the unsaturated cluster Os3(CO

Abstract:
Le motif spiroacétal est une structure présente dans le squelette de nombreuses molécules naturelles possédant des activités biologiques variées et pour laquelle il existe de nombreuses voies de synthèse. En revanche, son analogue azoté, le motif spiroaminal a été beaucoup moins étudié. Le premier de nos objectifs a consisté à développer une voie de synthèse énantiosélective, la plus générale possible, de ce motif. La stratégie retenue repose sur une étape clé de spirocyclisation acido-catalysée d’aminohydroxycétones issues de l’alkylation séquentielle de l’acétone N,N-diméthylhydrazone par di
