1,2-Dihydro-1,2-oxaborine: A Boron−Oxygen Heterocycle Isoelectronic with Benzene
摘要:
1,2-Dihydro-2-phenyl-1,2-oxaborine (1b) has been prepared by the reaction of (2,3-dihydro-1,2-oxaborol-3-yl)potassium (8) with methylene chloride and KN(SiMe3)(2). Structural characterization of the phenyl-Cr(CO)(3) complex 9 suggests that the 1,2-dihydro-1,2-oxaborine ring has a pi-delocalized structure.
