Abstract
We synthesized a dialane(4) compound (2) stabilized by double-layer N-P ligands. Upon reduction with KC8, compound 2 demonstrates solvent-dependent reactivity: in THF, it undergoes C—O bond cleavage to yield product [MeN(CH2CH2NPiPr2)2Al(CH2)4O]2K2; whereas in a THF/toluene mixture, it results in the activation of the methyl C—H bond in toluene, forming product [MeN(CH2CH2NPiPr2)2AlH]2K2. We propose that these reactions involve an “Al(I)” intermediate, which facilitates oxidative addition with either the C—O bond of THF or the C—H bond of toluene.
