阳离子π-烯丙基钯配合物[(η3-C3H5)Pd(CoD)]+[PF 6]-催化1，6-庚二炔衍生物的硅氢化反应生成1-亚甲基-2-(硅亚甲基)环戊烷，HSiMe n Cl3-n(n=0-2)同样适用于环化-硅氢化反应.在相同的反应条件下，某些1，6-烯炔的反应速度比1，6-二炔快，而9-氧杂-1-十二烯-6，11-二炔在二炔或烯炔部分进行了竞争性的环化-硅氢化反应，表明存在出人意料的高活性烯类化合物。
A cationic π-allylpalladium complex, [(η 3 -C 3 H 5 )Pd (cod)] + [PF 6 ] - , catalyzes hydrosilylation of 1,6-heptadiyne derivatives to form 1-methylene-2-(silylmethylene) cyclopentanes, HSiMe n Cl 3 - n (n = 0-2) being equally applicable to this cyclization-hydrosilylation. Certain 1,6-enynes react faster than 1,6-diynes under same reaction conditions, and 9-oxa-1-dodecene-6,11-diyne undergoes competitive cyclization-hydrosilylation at either diyne or enyne moiety, indicative of an unexpectedly high-reactive ene counterpart.
