Rhodium(III) complexes comprising monoanionic C,C,C‐tridentate dicarbene ligands activateSiHbonds and catalyse the hydrolysis of hydrosilanes to form silanols and siloxanes with concomitant release of H2. In dry MeNO2, selective formation of siloxanes takes place, while changing conditions to wet THF produces silanols exclusively. Silyl ethers are formed when ROH is used as substrate, thus providing

The reduction ofallylpalladium(II)chloride dimer (APC) to a Pd(0) species can be effected by reaction with alkali metal silanolates. The reduction is extremely rapid in the presence of chelating bisphosphine ligands and for a variety of silanolates.
烯丙基氯化钯 (II) 二聚体 (APC) 还原为 Pd(0) 物质可以通过与碱金属硅烷醇盐反应来实现。在螯合双膦配体和各种硅烷醇化物存在的情况下,还原速度非常快。

The reaction of allylic or benzylic alcohols 1 with n-butyllithium followed by treatment with lithium powder and a catalytic amount of DTBB (5 mol %) in THF at room temperature gives a solution of the corresponding alkyllithium reagent, which reacts in situ with different electrophiles to yield the expected products 2. Alternatively, the O-silylated derivatives of the same alcohols are lithiated under Barbier-type reaction conditions to afford the same reaction products with better yields.
