Synthesis of betaines containing the+P−C−Si−S− and+P−C−C−S− fragments and their characterization by multinuclear NMR spectroscopy [I. Borisova, N. Zemlyanskii, A. Shestakova, Yu. Ustynyuk, E. Chernyshev] A method for the synthesis of a new class of betaines,viz., R3 1P+CR2R3SiR4R5S−, was developed. The experimental evidence for the intermediate formation of betaines R3 1P+−CR2R3−CR4R5−S− in the Wittig reaction for a series of thiocarbonyl compounds was obtained. A comparative analysis of the NMR spectra of betaines containing the+P−C−Si−S− and+P−C−C−S− fragments was performed.
