1.Mixed anhydrides of dialkylborinic with saturated and unsaturated carboxylic acids were prepared. The mixed anhydride of dibutylborinic and methacrylic acids is capable of polymerizing and copolymerizing with certain monomers in presence of initiators.2.In the reaction of trialkylborines with carboxylic acids in equimolecular proportions, as well as the above mixed anhydrides, mixed pyroboronic-carboxylic anhydides, namely dialkylboron acetate, propionate, and benzoate, were isolated.3.As a result of the reaction of trialkylborines and trialkylaluminums with dicarboxylic acids the mixed anhydrides bisdibutylboron adipate, bisdipropylboron adipate, bisdibutylboron azelaate, and bisdibutylaluminum adipate were obtained; from equimolecular amounts of triisobutylaluminum and adipic acid a product of possibly polymeric character was formed. |
