摘要:
Hydrolysis reactions of MCl3( CCH=C(ArCl)(2))(PPh3)(2) (M = Ru, Os) were investigated. Treatment of OsCl3( CCH=C(o,o'-C6H3Cl2)(2))(PPh3)(2) with water produced the six-membered metallacycle OsCl(kappa C,kappa Cl-CH=C(o,o'-C6H3Cl2)(2))(CO)(PPh3)(2). Reactions of MCl3 ( CCH=C(o-C6H4Cl)(2))(PPh3)(2) (M = Ru, Os) produced the related six-membered metallacycles MCl(kappa C,kappa Cl-CH=C(o-C6H4Cl)(2))(CO)(PPh3)(2).
