在CF_3SO_3 Ag存在下,螯合物(RuCl_2 {κ 2(P,O)-i-Pr_2 PCH_2CH_2 OMe}_2)(1)与1当量的C_6H_4(C;CH)_2-p(4)反应,得到单核亚乙烯基化合物(RuCl(C= CHC_6H_4-p-C;CH){κ 2(P,O)-i-Pr_2 PCH_2CH_2 OMe}_2)(CF_3SO_3)(3)。从1和0.5当量的4出发,得到双核双亚乙烯基配合物(RuCl{κ 2(P,O)-i-Pr 2 PCH 2CH 2 OMe}2(C= CHC 6 H4-p-CH=C)RuCl{κ 2(P,O)-i-Pr 2 PCH 2CH 2 OMe}2)(CF 3SO 3)2(6).相关化合物(RuCl{κ 2(P,O)-i-Pr 2 PCH 2CH 2 OMe}2(C= CHC 6 H4-m-CH=C)RuCl{κ 2(P,O)-i-Pr 2 PCH 2CH 2 OMe}2)(CF 3SO 3)2(7)由1.0.5当量的C6 H4(C;CH)2-m(5)和三氟甲磺酸银制备。2或3与通过加入14-电子片段,以2:1的摩尔比生成(RhCl(P-i-Pr 3)2)2(8(RhCl(P-i-Pr 3)2)与未配位的C-C三键形成异双核配合物(RuCl{κ 2(P,O)-i-Pr2PCH2CH2OMe}2(C= CHC_6H_4-m/p-C; CH)氯化铑(P-i-Pr 3)2)(CF 3SO 3)(9,10),其在室温下缓慢重排,得到双(亚乙烯基)异构体(RuCl{κ 2(P,O)-i-Pr 2 PCH 2CH 2 OMe}2(C= CHC 6 H4-m/p-CH=C)RhCl(P-i-Pr 3)2)(CF 3SO 3)(11,12)。
The chelate complex (RuCl2{κ 2 (P,O)-i-Pr2PCH2CH2OMe}2 )( 1) reacted, in the presence of CF3SO3Ag, with 1 equiv of C6H4(C;CH)2-p (4) to afford the mononuclear vinylidene compound (RuCl(C=CHC6H4-p-C;CH){κ 2 (P,O)-i- Pr2PCH2CH2OMe}2)(CF3SO3 )( 3). From 1 and 0.5 equiv of 4, the binuclear bis(vinylidene) complex (RuCl{κ 2 (P,O)-i- Pr2PCH2CH2OMe}2(C=CHC6H4-p-CH=C)RuCl{κ 2 (P,O)-i-Pr2PCH2CH2OMe}2)(CF3SO3)2 (6) was obtained. The related compound (RuCl{κ 2 (P,O)-i-Pr2PCH2CH2OMe}2(C=CHC6H4-m-CH=C)RuCl{κ 2 (P,O)-i-Pr2PCH2CH2OMe}2)(CF3SO3)2 (7) was prepared from 1, 0.5 equiv of C6H4(C;CH)2-m (5), and silver triflate. The reaction of 2 or 3 with (RhCl(P-i-Pr3)2)2 (8) in the molar ratio of 2:1 yields, by addition of the 14-electron fragment (RhCl(P- i-Pr3)2) to the uncoordinated C—C triple bond, the heterobinuclear complexes (RuCl{κ 2 (P,O)-i-Pr2PCH2CH2OMe}2(C=CHC6H4-m/p-C;CH)RhCl(P-i- Pr3)2)(CF3SO3 )( 9, 10) which slowly rearrange at room temperature to give the bis(vinylidene) isomers (RuCl{κ 2 (P,O)-i- Pr2PCH2CH2OMe}2(C=CHC6H4-m/p-CH=C)RhCl(P-i-Pr3)2)(CF3SO3 )( 11, 12).
