Abstract
The syntheses of the new asymmetric substituted boron amidines [N'-(2,6-diisopropylphenyl)-N-(pentafluorophenyl)acetimidamide]bis(pentafluorophenyl)borate () and [N'-(2,6-diisopropylphenyl)-N-(4-cyanophenyl)acetimidamide]bis(pentafluorophenyl)borate () were achieved by reaction of one equivalent of HB(C6F5)2 and the respective amidines and . These adducts, bearing electron withdrawing groups, showed thermally induced H2 elimination forming the four-membered cyclic diazaborate derivatives and . These new species were characterized by spectroscopic methods. X-ray diffraction studies have been carried out on , and . To prevent undesired reactions at the nitrile group, one equivalent of B(C6F5)3 was added to yielding the -B(C6F5)3 nitrile adduct . Compound underwent thermally induced dehydrogenation to give the four-membered cyclic diazaborate derivative . CO was inserted into the ring systems of and forming the five-membered diazaborolone derivatives and . Phenylacetylene reacted stoichiometrically with the asymmetric substituted boron amidines , and to give styrene by double H transfer.
