Abstract

1,3-Diyne compounds are versatile building blocks in the construction of linearly π-conjugated acetylenic oligomers and polymers,(1) natural products,(2) electronic and optical materials,(3) and molecular recognition systems.(4) They are obtained either by Cu-mediated homocoupling reactions including Glaser coupling,(5) Eglinton coupling,(6) Hay coupling,(7) and related modified methods,(8, 9) or by Pd-catalyzed homocoupling reactions.(10, 11) ...
