【Abstract】 It was found that methallyldimethylaluminium（A）adds to 5-decyne in the presence of zirconium complex（Cp₂ZrCl₂）.Treatment of the initially formed intermediate with an acid gives pentadiene derivative（1）.The reaction is highly stereoselective and proceeds exclusively by syn-addition.Methallylzinc chloride（B）adds to 6-iodo-1-hexyne without the presence of any kindsof transition metal complexes.Some new monocyclic and bicyclic compounds（2,3,4）weresynthesized via allylzincation.更多还原
