Heating alkylboric acids with acetic anhydride gave oxybis [acetoxyalkylborines].
Oxybis [acetoxyalkylborines] reacted with esters of alkylboric acids at 160—185° to form alkylboric anhydrides.
When heated with a phenylboric ester, oxybis [acetoxy-n-propylborine] formed a mixture of n-propylboric and phenylboric anhydrides.
When heated with an n-propylchloroboric ester, Oxybis [ acetoxy-n-propylborine] formed n-propylboric anhydride.
