Abstract

Efficient and practical synthesis of a variety of 1-iodo-4-(trimethylsilyl) but-1-en-3-yne derivatives 1 and 2 with trans-and cis-olefin configuration was described. Their repeated use as building blocks allowed the facile synthesis of trans-and cis-oligoenynes, respectively. Development of a highly practical method for preparing monodisperse trans-and cis- oligoenediynes having the effective conjugation length was also accomplished by using 5 ...
