(equation presented) Methyldihydrodithiepins are converted into the corresponding carboxaldehydes via a simple and efficient oxidation by oxygen in carbon tetrachloride. The reaction is not a radical chain process. The proposed mechanism involves photoind

Enantioselective sulphoxidation of a wide range of 2-substituted-1,3-diathianes has been carried out using modified Sharpless conditions to furnish the corresponding sulphoxides in optically enriched form. Deacylation of 2-acyl-1,3-dithiane 1-oxide deriva

Solutions of the title compounds R-Ti(OR')3 (1) are generally available from organolithium (or magnesium) derivatives according to equation 1.It is shown (table 1) that some heterosubstituted organotitanium compounds are more stable thermally than their lithium counterparts.The reagents 1 are highly selective carbonylophiles (Tables 1 and 2), their reactivity can be modified by variation of the R'O-group (Table 3) and with the chiral (S)-2-methyl-1-butoxy group an enantioselective addition can be achieved.
