摘要

It was surprisingly found that the highly active allyl alcohol redox isomerization catalyst [RuCp (PPh3) 2](OTs) upon addition of a catalytic amount of a strong acid can change its catalytic action fully to the selective O-allylation of phenols with allyl alcohol. High turnover numbers (75,000 based on phenol; 200,000 based on allyl alcohol) are reached, and the catalyst is very stable in the presence of substrate. Addition of triphenylphosphine to the ...
