A very general preparative method for homoallyllithiums consists of reductive lithiation of homoallylithiums consists of reductive lithiation of homoallyl phenyl sulfides by lithium 4,4'-di-tert-butylbiphenylide.The sulfides can be prepared by a variety o

Dithioacetals were synthesized from carbonyl compounds and thiols in the presence of polyphosphoric acid trimethylsilyl ester (PPSE).Aldehydes, ketones, and trioxane could be used as carbonyl compounds, and aromatic, primary, secondary, and tertiary thiols were applicable in the present reaction.The reaction between cyclohexanone and t-butyl thiol afforded a mixture of corresponding dithioacetal and t-butylcyclohexenylsulfide.

The α-phenylthiosilanes (2) have been used to prepare the α-silyl anions (1) by reaction with lithium naphthalenide; subsequent condensation with a carbonyl compound gave the alkene (8) via the Peterson reaction.The α-phenylthiosilanes (2) were prepared from n,n-bis(phenylthio)acetals (4) by reaction with lithium naphthalenide and chlorotrimethylsilane.The n,n-bis(phenylthio)acetals (4) were obtained, in turn, from 1,1-bis(phenylthio)acetals (5) by anion formation with butyl-lithium-N,N,N',N'-tetramethylethylenediamine complex in hexane followed by reaction with an alkyl halide.The Peterson reaction was also used to prepare vinyl sulphides (9) and vinyl sulphones (13).

Bis(phenylthio)acetals can be lithiated with n-butyllithium - N,N,N'N'-tetramethylethylenediamine complex in hexane and consequently alkylated.
