CONTINUOUS DEPENDENCE AND UNIQUENESS IN CAUCHY'S PROBLEM FOR FIRST ORDER, NON-LINEAR, PARTIAL DIFFERENTIAL EQUATIONS, PART II
MARYLAND UNIV COLLEGE PARK
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-C5H52Fe2CO4. The reaction of diphenylborinic acid with boron trichloride produced an unidentified yellow liquid which solidified upon redistillation.
