Reaction Conditions: 5 mol% Ni(OAc)2, 5 mol% L2 ligand, 10 mol% KO-t-Bu, 15 mol% BF3•OEt2, 1.1 eq silane at room temperature for 16h. Yields determined on purified products. In all cases, a single regioisomer was detected by 1H NMR on crude reaction mixtures. Hydrolysis Conditions: 15% NaOH (aq) and MeOH at room temperature for 8h.
Yield determined by 1H NMR versus mesitylene internal standard.
TBAF deprotection used for desilylation.
