A novel Lewis-acid-catalyzed 1,2-OMe shift reaction of an acetylenic ether on a dipalladium framework. X-ray structure of [Pd2Cl2(μ−dppm)2(μ−CC(OMe)(Me))]
摘要:
Treatment of [Pd2Cl2(mu-dppm)(2)] with MeOC=CMe in CH2Cl2 in the presence of catalytic amounts of HBF4 . Et(2)O led to the formation of [Pd2Cl2(mu-dppm)(2)(mu C=C(OMe)(Me))] via a 1,2-OMe shift reaction. The complex was characterized crystallographically.
