Abstract

Abstract Under mild conditions, trialkylalanes (Et 3 Al and Bu i 3 Al) in chlorine-containing solvents (CH 2 Cl 2 or ClCH 2 CH 2 Cl) react with cyclic acetals and orthoformates to form glycol monoethers and dialkylacetals, respectively, in high yields. The 1 H NMR spectroscopic data demonstrate that CH 2 Cl 2 or ClCH 2 CH 2 Cl interacts with Bu i 3 Al.
