Titanocene(II)-promoted cross-coupling between (Z)-alkenyl methyl sulfones and terminal allenes produced 1,4-dienes regioselectively via the formation of 2-alkylidenetitanacyclopentanes. Preferential formation of E,Z-dienes was observed in the reaction using aryl-, amino-, and phosphinylallenes.
(Z)-链烯基甲基砜与末端异戊烯之间的钛茂(II)促进的交叉偶合通过形成2-烷基亚乙基二环戊烷而区域选择性地产生了1,4-二烯。在使用芳基-,氨基-和次膦基烯丙基的反应中观察到E,Z-二烯的优选形成。
