Reaction of ground-state aluminium atoms with diethyl ether. Electron spin resonance evidence for insertion into the CH and CC bonds

Abstract
Ground-state Al atoms react with diethyl ether on solid hydrocarbon surfaces at 77 K in a rotating cryostat to give several mononuclear aluminium(o) compounds. The magnetic parameters of two of these compounds are consistent with the formation of CH3CHAlH(OCH2CH3) and/or CH3CH2OCH2CH2AlH and CH3AlCH2OCH2CH3 produced by insertion of the Al atom into the CH and CC bonds of the ether. A third species could be CH3CH2OAlCH2CH3, given by insertion into the CO bond, but this assignment is somewhat tentative.
