2-Methylenepropane-1,3-diol first allylates an aldehyde exclusively at the allylic alcohol moiety at room temperature and then, at 50 °C, allylates another aldehyde also at the allylic alcohol moiety, in the presence of a catalytic amount of PdCl2(PhCN)2 with tin(II) chloride.
                                    2-甲烯基
丙烷-1,3
-二醇首先在室温下选择性地在
烯丙醇部分对醛进行烯丙基化,然后在50°C下,在催化量的PdCl2(PhCN)2和
氯化亚锡的存在下,再次在
烯丙醇部分对另一个醛进行烯丙基化。
