The title compound was generated by and reacted with (1) a series of reagents which have basic as well as nucleophilic properties and (2) a series of base/nucleophile combinations.Product yields of the isobutenyl derivative were generally low to very good, and the best results (89percent) were obtained by using a 1:2 ratio (3 equiv total) of nBuLi:LiPPh2.Synthetic utility of the reaction is optimized as it approaches a situation in which the base/nucleophile combination is composed of one compound which is both a strong base and a poor nucleophile and another compound which is both a weak base and a good nucleophile.

Conditions were developed for the convinient preparative synthesis of 2-methylpropenyl sulfides and their oxygen and nitrogen analogs on the basis of reactions of thiols, alcohols, and lactams with isobutyraldehyde in excess of chlorotrimethylsilane.By-pr

Acyclic acetals and 1,1-di(alkylthio)alkanes enter into exchange reactions in the presence of aprotic acids and of the KU-2 cation-exchange resin with the formation of the unsymmetric acetals and 1-alkoxy-1-alkylthioalkanes.In reaction with ethylal di(ethylthio)methane forms 3,5,7-trioxanonane in addition to ethylthioethoxymethane. 2-Methyl-4-thia-2-hexene was found in the products from the reaction of 1,1-di(ethylthio)-2-methylpropane with methylal.
