AI Article Synopsis
- Gold complexes were previously considered ineffective in homogeneous catalysis, often labeled as "catalytically dead."
- Recent findings show that cationic phosphanegold(I) complexes can effectively catalyze reactions, particularly the addition of alcohols to alkynes.
- These complexes achieve impressive turnover rates, reaching up to 1.5 seconds with total turnover numbers as high as 10.
Article Abstract
Gold complexes are almost unknown in homogeneous catalysis, and for a long time gold was even thought of as "catalytically dead". This is clearly not the case for cationic phosphanegold(I) complexes (see reaction below), which can catalyze the addition of alcohols to alkynes with turnover frequencies up to 1.5 s and total turnover numbers up to 10 ! R=H, alkyl, Ph, CH OH.
