Abstract : DERIVATIVES OF DIALKYL AND DIARYLBORON CYANIDES: Di-alpha-naphthylborinic acid was prepared and reacted with hexacyanocobaltic acid. An attempt was made to prepare di-tert-butyl borinic acid by reacting a boron trifluoride-ether complex in anhydrous ether with tert-butylmagnesium chloride. A proton nuclear magnetic resonance spectrum will be used to determine whether one of the fractions obtained is the desired product. PREPARATION AND INVESTIGATION OF COMPOUNDS CONTAINING BORON-TO-TRANSITION-METAL BONDS: Dimesitylborinic acid was prepared by slowly adding boron trifluoride etherate to a tetrahydrofuran solution of mesitylmagnesium bromide at room temperature. Other compounds prepared were butyldiphenylborinate, iso-butyldi-alphanaphthylborinate, and (pi-C5H5)2Fe2(CO)4. The reaction of diphenylborinic acid with boron trichloride produced an unidentified yellow liquid which solidified upon redistillation.
