Synthesis, structure, and reactivity of a gold carbenoid complex that lacks heteroatom stabilization

Hydride abstraction from the neutral gold cycloheptatrienyl complex [(P)Au(η1-C7H7)] (P=P(tBu) 2(o-biphenyl)) with triphenylcarbenium tetrafluoroborate at -80 C led to the isolation of the cationic gold cycloheptatrienylidene complex [(P)Au(η1-C7H6)]+ BF 4- in 52 yield, which was characterized in solution and by single-crystal X-ray diffraction. This cycloheptatrienylidene complex represents the first example of a gold carbenoid complex that lacks conjugated heteroatom stabilization of the electron-deficient C1 carbon atom. The cycloheptatrienylidene ligand of this complex is reactive; it can be reduced by mild hydride donors, and converted to tropone in the presence of pyridine N-oxide. Hydride abstraction from the neutral gold cycloheptatrienyl complex 1 (P=P(tBu)2 (o-biphenyl)) with Ph3C+ BF 4- formed the cationic gold cycloheptatrienylidene complex 2, which was characterized by single-crystal X-ray diffraction. The cycloheptatrienylidene ligand of 2 is reactive; it can be reduced by mild hydride donors, and converted into tropone in the presence of pyridine N-oxide.

A PHOTO-INDUCED REACTION BY VISIBLE LIGHT VIA A CHARGE TRANSFER COMPLEX

The reduction of tropylium cation (Tr+) with concomitant oxidation of O,O'-dialkyldithiophosphate anions (dtp-) have been achived by visible irradiation of their acetonitrile solution in presence of a bipyridium dication; the later via its charge transfer complex with dtp- acts as a light-harvest and as an electron relay.
