  Preparation of trihydridostannyl complexes of rhenium stabilised by isocyanide ligands

  摘要：

  Mixed-ligand complexes [ReBr(CO)(2)(CNR)(n)L(3) (n)] (1-4) [R = 4-CH(3)OC(6)H(4), 4-CH(3)C(6)H(4), C(CH(3))(3); L = P(OEt)(3), PPh(OEt)(2); n = 1, 2] were prepared by allowing carbonyl compounds [ReBr(CO)(4)L] and [ReBr(CO)(3)L(2)] to react with an excess of isocyanide. Treatment of these bromocomplexes [ReBr(CO)(2)(CNR)(n)L(3 n)] with SnCl(2) center dot 2H(2)O yielded the trichlorostannyl derivatives [Re(SnCl(3))(CO)(2)(CNR)(n)L(3 n)] (5-8). Trihydridestannyl complexes [Re(SnH(3))(CO)(2)(CNR)(n)L(3 n)] (9-12) were prepared by allowing trichlorostannyl compounds 58 to react with NaBH(4) in ethanol. The trimethylstannyl derivative [Re(SnMe(3))(CO)(2)(CNC(6)H(4)-4CH(3)){PPh(OEt)(2)}(2)] (13b) was also prepared by treating [Re(SnCl(3))(CO)(2)(CNC(6)H(4)-4-CH(3)){PPh(OEt)(2)}(2)] with an excess of MgBrMe in diethylether. Reaction of the tin trihydride complexes [Re(SnH(3))(CO)(2)(CNR)(n)L(3) (n)] (9-12) with CO(2) (1 atm) led to dinuclear OH-bridging bis(formate) derivatives [Re{Sn(OC(H)=O)(2)(mu-OH)}(CO)(2)(CNR)(n)L(3 n)](2) (14, 15). The complexes were characterised spectroscopically (IR, (1)H, (31)P, (13)C, (119)Sn NMR) and by X-ray crystal structure determination of [Re(SnH(3))(CO)(2){CNC(CH(3))(3)}{PPh(OEt)(2)}(2)] (10b).
