Under mild conditions (25 °C, 5 mol% cat.), highly selective homo- and cross-desilacoupling of aryl and benzyl primary silanes to secondary silanes was achieved by the use of the heteroleptic barium aminobenzyl complex [(TpAd,iPr)Ba(CH2C6H4NMe2-o)] (TpAd,iPr = hydrotris(3-adamantyl-5-isopropyl-pyrazolyl)borate) (1) as a catalyst. Dihydrosilanes originating from catalytic redistribution and cross-desilacoupling reactions were isolated in fine yields, which demonstrates the feasible application of the barium complex in the syntheses of secondary aryl- and benzylsilanes.

Rare-earth metal tris(aminobenzyl) complexes Ln(CH2C6H4NMe2-o)3 (Ln = La, Y) were grafted onto the dehydroxylated periodic mesoporous silica support SBA-15 to generate the organometallic-inorganic hybrid materials Ln(CH2C6H4NMe2-o)3@SBA-15 (Ln = La (2a), Y (2b)), which demonstrated extremely high selectivity (>99%) in catalyzing the redistribution of primary arylsilanes to secondary arylsilanes without the requisition of strict control of the reaction conditions. The hybrid materials still showed a perfect selectivity and activity after three catalytic cycles.
