摘要

transformation and a desire to gain a greater understanding of these processes in general have led us to explore the thermal chemistry of the hydrocarbon l. 4 (Z)-1, 2, 4-Heptatrien-6- yne (1) was synthesized as follows. Propargyl alcohol and (Z)-1, 2-dichloroethylene (1.1 equiv) were coupled at 0" C with tetrakis (tripheny1phosphine) palladium (0.05 equiv)- cuprous iodide (0.20 equiv) in ether containing npropylamine (4.0 equiv) to provide the (Z) ...
