The smooth conversion of the readily available compounds, H2C=C(OMe)-CR'2-X (1; X=OC(O)Me or OS(O)Me), with R-ZnCl reagents, using Pd4 as catalyst, is described.It is shown that via this route several 3-methoxy-1,3-dienes H2C=C(R)-C(O)Me)=CR'2 (2), in which the group R is 1-alkenyl, aryl, 1,2-alkadienyl or 1-alkynyl, can be prepared.The results obtained with R-Cu or R2CuM were generally inferior to those found with the zinc compounds.
