The conversion of aldehydes RCHO into terminal conjugated dienes RCHCHCHCH2 with (E) stereochemistry was carried out at room temperature with 1-bromo-3-iodopropene in the presence of SnCl2. Starting from an unsaturated aldehyde, a terminal conjugated triene was obtained in the same conditions.
醛转化为RCHO终端共轭二烯RCHCHCHCH 2与(E)的立体化学在室温下与1-溴-3- iodopropene中的SnCl的存在下进行2。从不饱和醛开始,在相同条件下获得末端共轭三烯。
