Preferred Abstract (Original): 

Dimanganese decacarbonyl catalyst has been evaluated in the reactions of HSiR3 (R = Et, OEt) with R'OH (R' = Me, Et, i-Pr, t-Bu and benzyl), under various conditions. The order of reactivity of the alcohols decreases when more bulky alkyl groups are used, and that of the silanes increases if a more electron-withdrawing group (OEt) is used. Kinetic analysis indicates that the reaction is first order with respect to the silane, to the alcohol and to the catalyst. The effects of varying the solvent and adding a phosphine ligand have also been investigated.
