Highly regioselective thioformylation of terminalacetylenes with thiols and carbon monoxide has been developed by the use of rhodium(I) complexes as the catalyst: formyl and thio groups are introduced into the terminal and inner positions of acetylenes, respectively. The thioformylation is performed in the presence of a catalytic amount of rhodium(I) complexes, such as RhH(CO)(PPh3)3, RhCl(PPh3)3

(Z)-1,3-Bis(arylthio)-2-alken-1-ones (1) are chemoselectively reduced to the corresponding aldehydes (3) by n-Bu3SnH with the aid of palladium catalysts under the very mild reaction conditions.
