Hydrogallation of Alkynes: Syntheses of Carbon−Gallium Cages Possessing Heteroadamantane Structures
摘要:
Treatment of the alkynes R'CdropCH (R' = Me, n-Pr) with dialkylgallium hydrides, R2GaH (R = Me, Et), yielded symmetrical carbon-gallium cage compounds with release of dihydrogen and subsequent addition of Ga-H to the CdropC triple bonds. Heteroadamantane-type compounds (GaR)(6)(CR')(4) were formed in which the positions of the methylene bridges of the carbon skeleton in adamantane were occupied by coordinatively unsaturated, tricoordinate gallium atoms.
