Carbene complexes of cycloplatinated 1H-indole-1-methyl-2-(2′-pyridine). The crystal and molecular structure of σ-{Pt[1H-indole-1-methyl-2-(2′-pyridinyl-C3,N′](DMSO)Cl} and of σ-{Pt[1H-indole-1-methyl-2-(2′-pyridinyl-C3,N′)][C(OCH2CH3)(CH2C6H5)]Cl}
摘要:
Reaction of 1-methyl-2-(2'-pyridinyl)-1H-indole (1) with PtCl2(DMSO)(2) (DMSO = dimethylsulfoxide) gave the cycloplatinated product 2; X-ray structure determination of 2 showed a metallation to platinum via the C3 carbon of the indole nucleus, which is chelated to the metal via the pyridine nitrogen atom. Compound 2 reacts with neutral ligands such as CO, Bu'NC, styrene and phenylacetylene, to give compounds 3-6 respectively, where DMSO is replaced by the neutral ligands. The phenylacetylene derivative 6 reacts with ethanol to give the carbene complex 7, whose X-ray structure has been determined. Related carbene complexes with other alcohols and other acetylenic derivatives have also been synthesised. (C) 2000 Elsevier Science S.A. All rights reserved.
