catalyst the stereo-selective formation of cis- and trans-[2H4]but-2-ene is observed in the metathesis of equimolar mixtures of cis-[2H0]- and -[2H8]but-2-ene, and trans-[2H0]- and -[2H8]-but-2-ene, respectively; the yields of cis- and trans-but-2-ene from reactions of the corresponding pent-2-ene isomers are in good agreement, but metathesis of propene selectively yields trans-but-2-ene.
以MoO x / β- TiO 2为催化剂,在顺式-[ 2 H 0 ]-和-的等摩尔混合物复分解中观察到顺式-和反式-[ 2 H 4 ]丁-2-烯的立体选择性形成。[ 2 H 8 ]丁-2-烯和反式-[ 2 H 0 ]-和-[ 2 H 8 ]-丁-2-烯;顺式和反式的产量来自相应的戊-2-烯异构体的反应生成的-丁-2-烯非常吻合,但是丙烯的复分解选择性地产生了反式-丁-2-烯。
