Substituted boryl, BX2, substituent effects on the ultraviolet, hydrogen NMR and photoelectronspectra of benzene are compared with the results of modified CNDO/2 calculations. The substituents BF2, BCl2, B(OR)2 and BR2 are characterized by the relative degree of the electronegativity of X and π bonding to boron. Intramolecular charge transfer UV transitions are identified where BX2 is BCl2 or BR2
