transformation. The reactions of [YMe3]n and [(C5Me5)YMe2]3 indicated occurrence of hydrido transfer for H2AlMes* and led to product mixtures for HAl(CH2SiMe3)2. Following the reaction of HAlMe2 with these compounds as well as the half-sandwich derivatives (C5Me4R)Y(AlMe4)2 (R = Me, SiMe3) indicated reversible hydrido binding, leading ultimately to the formation of insoluble hydride clusters.
