资源简介:
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 π-delocalized structure.
