Syntheses, x-ray crystal structures, and solution behavior of monomeric, cationic, two-coordinate gold(I) π-alkene complexes


Journal Article

Treatment of a suspension of (IPr)AuCl [IPr = 1,3-bis(2,6- diisopropylphenyl)imidazol-2-ylidine] and AgSbF 6 (1:1) with isobutylene at room temperature for 12 h led to isolation of [(NHC)Au(∇ 2-H 2C CMe 2)]+ SbF 6 - (1a) in 98% yield, which was characterized by spectroscopy and X-ray crystallography. A number of cationic gold π-alkene complexes were isolated employing a procedure similar to that used to isolate 1a, two of which were analyzed by X-ray crystallography. Spectroscopy, X-ray crystallography, and alkene binding studies were in accord with a gold-(π-alkene) interaction dominated by @-donation from the alkene to gold.
