Al atoms react with symmetric cyclic and acyclic ethers at 77 K in a rotatingcryostat to give a host of mononuclear organoaluminium compounds. Magnetic parameters determined from EPR spectra given by Al atoms and acyclic ethers are consistent with the formation of novel C—C and C—H aluminium atom insertion products. A third species has been tentatively assigned to the product given by Al atom insertion

Ground-state Al atoms react with diethylether 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 CCbonds of the ether. A third species
