We report first the complete study of the reactions of [CpMo(CO)2]2 (Mo≡Mo) (1, Cp = η5-C5H5) with salt-free phosphorus ylides Ph3P=CHR (2, Ph = C6H5; R = H (2a), CH3 (2b), C3H7 (2c), C6H5 (2d)) and with the Nal-adducts of the ylides Ph3P=CMe2 (Me = CH3), PhMe2P=CH2 and (PhO)3P=CH2. With 2, products of the type Cp(CO)2LMo-MoL(CO)2Cp (7, L = ylide) were obtained, and the salt adducts gave addition compounds of the type Cp(CO)2LMo-MoL(CO)2Cp-2NaI (12, L = ylide). These very reactive products represent novel bisphosphonioalkyl complexes, and were characterized by IR, mass and 1H NMR spectrometry.

Abstract:
Carbonyl olefinations are among the most important organic syntheses that form C=C bonds, as they usually have high yields and in addition offer excellent stereoselectivity. Due to these advantages, carbonyl olefinations have important pharmaceutical and industrial applications. These reactions contain an additional step of an α-functionalized carbanion to an aldehyde or ketone to produce alkenes, but syntheses performed using metal carbene complexes are also known. The Wittig reaction is an example of carbonyl olefination, one of the best ways to synthesize alkenes. This involves the chemical

Abstract:
The synthesis, theoretical study and a kinetics and mechanistic investigation are described as a one-pot condensation reaction between benzamide and acetylenic esters in the presence of triphenyphosphine to generate a novel stable phosphorus ylides. For the first time, theoretical calculations have been employed to assign the most stable isomers ( Z or E) of phosphorus ylides 4a-c by AIM and NBO theory, in which Z-4(a,b) are the more stable forms, whereas Z-4c appears as a single isomer. In these cases, the 1H, 13C and 31P NMR spectra of these ylides are consistent with the results obtained fr

Abstract:
Abstract Treatment of (Me2N)3PCHSiMe3 with Me3SiOTf (OTf = triflate) affords the phosphonium salt [(Me2N)3PCH(SiMe3)2]OTf (2a), which can be converted into the correspond­ing ylide (Me2N)3PC(SiMe3)2 (3a) in high yield using NaN(SiMe3)2. The compounds with SiMe2Ph substituents (2, 3b) are obtained following an analogous procedure. The ylide (Me2N)3PC[Si(OMe)3]2 (3c) is available in 50% yield by direct transylidation of (MeO)3SiOTf with (Me2N)3PCH2 in the molar ratio 2:3, with [(Me2N)3PMe]OTf as the by-product. Com­pound 3c is a distillable liquid, but 3a,b are crystalline solids the structure o
