CMeCH 2 ) 2 (dppb)] catalysis to give 2-(trans-2-ethoxycyclopropyl)ethenyl esters 13 (69-92%, 3 examples). (1-Hydroxycyclopropyl)ethyne (14), under catalysis by [Ru(O 2 CH)(CO)2(PPh 3 )] 2 , reacts with carboxylic acids to yield 1-acetylcyclopropyl esters 15 (49-74%, 4 examples) by Markovnikov-sense addition and intramolecular transesterification. Anti-Markovnikov- and Markovnikov-sense addition of carboxylic
