    摘要:
    Treatment of [IrCl(C8H14)(2)](2) (5) with i-Pr(2)PCH(2)CH(2)OMe (6) leads to the formation of the octahedral hydridoiridium(III) complex [IrHCl{kappa(2)(C,P)-CH(2)OCH(2)CH(2)Pi-Pr-2} {kappa(2)(P,O)-i-Pr-2-PCH(2)CH(2)OMe}] (8), which according to the X-ray structure analysis contains both a five- and a six-membered chelate ring. In contrast to 6, the phosphinoamine i-Pr(2)PCH(2)CH(2)NMe(2) (7) reacts with 5 to give the expected square-planar iridium(I) compound trans-[IrCl{kappa(P)-i-Pr(2)PCH(2)CH(2)NMe(2)}{kappa(2)(P,N)-i-Pr(2)PCH(2)CH(2)NMe(2)}] (9), which in solution at room temperature is nonfluxional on the NMR time scale. Reaction of 9 with CO yields four-coordinate trans-[IrCl(CO){kappa(P)-i-Pr(2)PCH(2)CH(2)NMe(2)}(2)] (10), while on treatment of 9 with HCl in benzene the six-coordinate [IrHCl2{kappa(P)-i-Pr(2)PCH(2)CH(2)NMe(2)}{kappa(2)(P,N)-i-Pr(2)PCH(2)CH(2)NMe(2)}] (11) is obtained. Compound 11 is also one of the products of the reaction of 9 with CH2Cl2 which equally gives small quantities of the ionic bis(chelate) complex [IrCl2{kappa(2)(C,P)-CH(2)NMe(2)CH(2)CH(2)Pi-Pr-2}{kappa(2)(P,N)-i-Pr(2)PCH(2)CH(2)NMe(2)}]Cl (12). The chlorodihydrido and dichlorohydrido complexes [IrH(Cl)X{kappa(P)-i-Pr(2)PCH(2)CH(2)OMe}{kappa(2)(P,O)-i-Pr(2)PCH(2)CH(2)OMe}] (13, X = H; 14, X = Cl) are formed at room temperature almost instantaneously from 8 and H-2 or HCl, respectively. At 80 degrees C, the reaction of 8 (or 13) with methyl acrylate and methyl vinyl ketone affords the hydrido(vinyl)iridium(III) derivatives [IrHCl{kappa(2)(C,O)-CH=CHC(R)=O}{kappa(P)-i-Pr(2)PCH(2)CH(2)OMe}(2)] (15, R = OMe; 16, R = Me), whereas with HC=CR the alkynyl(hydrido) compounds [IrH(C=CR)Cl{kappa(P)-i-Pr(2)PCH(2)CH(2)OMe}{kappa(2)(P,O)-i-Pr(2)PCH(2)CH(2)OMe}] (17, R = Ph; 18, R = CO(2)Me) are obtained. Thermal or photochemical rearrangement of 17 and 18 leads to the formation of the isomeric vinylideneiridium(I) complexes trans-[IrCl(=C=CHR)-{kappa(P)-i-Pr(2)PCH(2)CH(2)OMe}(2)] (20,21) in good yield. The octahedral alkynyl(vinyl) compound [IrCl(C=CCO(2)Me)(CH=CHCO(2)Me){kappa(P)-i-Pr(2)PCH(2)CH(2)OMe}{kappa(2)(P,O)-i-Pr2PCH2CH2-OMe}] has been prepared from either 8 or 13 and excess HC=CCO(2)Me. Chloride abstraction of 20 and 21 with AgSbF6 affords the SbF6 salts of the cationic complexes [Ir(=C=CHR){kappa(P)-i-Pr(2)PCH(2)CH(2)OMe}{kappa(2)(P,O)-i-Pr(2)PCH(2)CH(2)OMe}](+) (22, 23), in which according to the X-ray structure analysis of 23 the vinylidene ligand and the methoxy unit are trans disposed.

    cis-alkynyl(silyl)platinum(II) complexes was prepared via the chemoselective C(sp)–Si bond cleavage of alkynylsilanes by a platinum(0) complex ligated with the P–N hemilabile bidentate ligand. The coordination of the triple bond to the platinum center triggers selective C(sp)–Si bond cleavage.
