[reaction: see text] The rhodium-catalyzedaddition of alkynes to 1,2-diketones, 1,2-ketoesters, and aldehydes provides a method for the synthesis of tertiary alkynyl alcohols under mild conditions. The reaction tolerates many functional groups (such as carboxylic acids) that are incompatible with other methods. The alkyneadditionreaction proceeds best using bulky phosphine ligands such as 2-(di
