The reactions of diphenyldiselenide and dialkyl disulfides with aldehydes in the presence of In–TMSCl have been investigated. Aliphatic aldehydes provide the corresponding selenoacetals and aromatic aldehydes lead predominantly to benzyl phenyl selenides on reaction with diphenyldiselenide. However, the reaction of dimethyl disulfide and diphenyl disulfide with both aromatic and aliphatic aldehydes

The reaction of organotitanium species prepared by the desulfurizative titanation of thioacetals with (C5H5)2Ti[P(OEt)3]2 in the presence of trialkyl(allyl)silanes gives γ-substituted allylsilanes with Z stereoselectivity.
在三烷基(烯丙基)硅烷存在下,通过硫代乙酸酯与 (C5H5)2Ti[P(OEt)3]2 的脱硫钛化反应制备的有机钛,可以得到 Z 立体选择性的δ-取代烯丙基硅烷。

Reaction of carboxylic acids with thexylphenylthioborane in methylene chloride at room temperature gives S,S′-diphenyl acetals in high yields and carboxylic esters are converted into phenyl sulfides in the presence of zinc iodide under similar conditions.
