  Zinc-metal promoted selective α-haloacylation and gem-bisacylation of alkyl aldehydes in the presence of chlorotrimethylsilane

  摘要：

  Treatment of a mixture of alkyl aldehydes (1) with acid chlorides (2) in the presence of zinc metal powder and a catalytic amount of chlorotrimethylsilane (TMSCl) in dichloromethane brought about highly facile and effective coupling to give selectively the corresponding alpha-haloacylation and gem-bisacylation products, alpha-haloalkyl carboxylates and 1,1-dicarboxylates (acylals), in good to excellent yields.

  Compounds useful as plasticizers and the synthesis thereof are disclosed. In general, the invention includes mixed alkyl/aryl asymmetric cyclic diesters where the aryl and alkyl ester moieties are attached to a cyclic structure at vicinal carbons. The invention also includes synthetic processes of making such compounds. Blends of these asymmetric cyclic diesters with other plasticizers are demonstrated to be of use in plasticizing polymers.
