The relative reactivities of Al-Al and Al-C bonds, Al2(i-Bu)4, have been examined employing the protonic reagents H3O+, HCl(g), toluene-3,4-dithiol, and HMn(CO)5. Excess H2O, pH 1, results in 100% cleavage of both Al-Al and Al-C bonds, whereas the Al-Al bond exhibits greater reactivity toward HCl(g). In a similar manner the -SH moiety also reacts more readily with the metal-metal bond. In contrast the weak acid HMn(CO)5 is unreactive toward Al2(i-Bu)4. The latter also reacts with a hydride source, B2H6, to afford an insoluble material with the empirical stoichiometry AlB2H4. On the basis of deuterolysis data, the molecular formulation AL2(BH2)4 is suggested with extensive intermolecular hydrogen bonding.
