Abstract
A dialkoxyvinylborane of the general formula H2C=CHB(OR)2, wherein R is an alkyl group, preferably containing 1 to 4 carbon atoms, is made by heating a solution of a metal trialkoxyvinylborate of the formula H2C=CHB(OR)3MgX, wherein X is a chlorine or bromine atom, in an anhydrous inert solvent having a boiling point higher than the decomposition temperature of the metal trialkoxyvinylborate until the latter is thermally decomposed and collecting the dialkoxyvinylborane which distils from the solution. The solvent may be substituted or unsubstituted hydrocarbon or an ether. Distillation of the dialkoxyvinylborane may be started as soon as the decomposition of the metal compound is reached, and by introducing fresh metal trialkoxyvinyl borate continuously to replace that which is decomposed, the process can be performed continously. Reaction temperatures of 150 DEG C. to 275 DEG C. are preferred and the process may be effected at atmospheric or reduced pressures. Examples describe the preparation of diethoxy-, diisopropoxy-, and di-n-butoxy-vinylboranes. Specification 856,856 is referred to.
