Chemistry of phosphorus ylides: Part 44 reaction of 1-trimethylsilyl-1H-imidazole with phosphorus reagents. A convenient synthesis of phosphorus silyl imidazoles

The reaction of 1-trimethylsilyl-1H-imidazole with nucleophilic active phosphacumulenes afforded imidazole silyl phosphoranylidenes or imidazole phosphoranylidenes according to the reaction conditions. The reaction of hexaphenylcarbodiphosphorane with 1-trimethylsilyl-1H-imidazole resulted in the formation of silyl phosphoranylidene phosphoranyl imidazole, silyl phosphoranylidene imidazole and triphenylphosphane. Moreover, Lawesson and Japanese reagents afforded imidazole phosphinothioic thioanhydrides.

Cumulated Ylides, VII. A Method for the Synthesis of α,β-Unsaturated Carboxylic Compounds

Phosphacumulene ylides 1 add alcohols, thiols, and NH-acidic compounds to form phosphoranes 3, which react with aldehydes to give esters, thiol esters, imidates, thioimidates, amidines, azolides, and sulfonamides of α,β-unsaturated carboxylic acids.
