Reactions of scandium atoms in hydrocarbon matrices

Abstract

Scandium atoms have been deposited in inert (adamantane, cyclohexane and deuteriocyclohexane) and reactive (benzene, deuteriobenzene and cyclohexene) matrices on a rotating cryostat at 77 K. The main paramagnetic product in the former matrices is a weakly bound Sc⋯H complex, whereas in the latter two types of complex are formed. When carbon monoxide is co-deposited with Sc the biscarbonyl is the main product. The ESR parameters of these species are reported, and possible structures are discussed.
