Alkynones as well as unsymmetrically substituted tolanes (diarylalkynes) can be rapidly generated in a one-pot fashion via sequential palladium catalysis. Terminal alkynes, formed in situ by protecting-group free palladium-catalyzed coupling of aryl iodides with ethynyl magnesium bromide, are subsequently transformed by Sonogashira coupling with aryl halides or aroyl chlorides to furnish unsymmetrically substituted alkynes in good to excellent yields.

A series of crown ether derivatives containing a biphenyl or cholesteryl moiety have been synthesized for the first time.The structural effects of these compounds on the formation of liquid-crystalline phases are discussed.We have found that benzo crown e
