complete characterization of the intermediate organoboranes by 75-MHz sup13}C NMR wasmore » achieved. A detailed discussion of the phenomena involved is presented. The observed results are attributed primarily to the additional steric effects imposed on an unsaturated system by a trialkylsilyl group when compared to a hydrogen atom at that position.« less
