Abstract
A mild and efficient method for the alkynylation of arylacetylenes with ketones promoted by tert-BuOK under solvent-free conditions was developed. The present green synthesis was applicable to many kinds of aromatic and aliphatic ketones providing good to excellent yields of tertiary propargylic alcohols.
