o-1-cycloalkenes with titanocene(II)-triethyl phosphite complex, reacted with styrene derivatives to produce (E)-1,4-dienes. Their reaction with vinyl-borane and -silane also produced 1-boryl- and silyl-1,4-dienes, which were transformed into 1-substituted 1,4-dienes through the palladium(0)-catalyzed or copper(I)-promoted reaction with organic halides.
通过用钛茂(II)-三乙基亚磷酸酯络合物对3-(芳硫基)-1-氯-1-环烯烃进行还原钛化反应生成的二茂钛环烯基与苯乙烯衍生物反应生成(E)-1,4-二烯。他们与乙烯基硼烷和-硅烷的反应还产生了1-硼基-和甲硅烷基-1,4-二烯,它们通过钯(0)催化或铜(I)-被转化为1-取代的1,4-二烯。促进了与有机卤化物的反应。
