Infrared spectroscopic study of very low pressure pyrolysis products of cyclosilthianes and 3,3-dimethyl-3-silathietane isolated in argon matrices. A new source of 1,1-dimethyl-1-silaethylene (Me2siCH2), thioformaldehyde (H2CS) and dimethylsilanthione (Me2SiS)
The products of very low pressure pyrolysis (VLPP) of hexamethylcyclotri-silthiane (I), tetramethylcyclodisilthiane (II) and 3,3-dimethyl-3-silathietane (III) were isolated in Ar matrices and were studied by IR spectroscopy. The only pyrolysis product of I was cyclosilthiane II, a dimer of transient dimethylsilanthione (Me2SiS) (IV). The starting material was recovered on pyrolysis of II. Thermal decomposition

decomposition of betaines R3P−CR1R2−SiR3R4−S− (1) follows two main pathways: (a) a Corey—Chaykovsky type reaction with elimination of Ph3P and generation of silathiirane (2) and (b) a retro-Wittig type reaction accompanied by elimination of R3P=CR1R2 and generation of silanethione R3R4Si=S (3). Highly reactive compounds2 and3 undergo subsequent transformations to give derivatives of tetrahydro-1,4-dithia-2
