Abstract

It is well known that the reactivity of Grignard reagents towards trialkyl orthoformates is rather low'-'): for the formation of an acetal to be successful it is necessary either to reflux the reaction mixture in ether for several hours or to distill the ether from the reaction solution and to cautiously heat the residue until a highly exothermic reaction begins. It has been shown that by using the mixed orthoformate CsHSO-CH (OC2H5),(1) an acetal could be easily ...
