The application of general reactions available for the synthesis of aryl-boranes to synthesis of boron-substituted heteroaromatic compounds is somewhat restricted by the presence of a sensitive heteroaromatic ring. The substitution reaction of heteroaryl-metallic compounds (1) with halo-boranes (2) has been used to synthesize five-membered ir-excessive het-eroarylboranes (3) (76CB1075) (Scheme 1). 

The reactions of boron-substituted heteroaromatic compounds may be formally classified into two types (1) reactions relating to the carbon-boron bond, and (2) all other reactions. Very few investigations have been reported concerning the latter. 

Section III,A emphasizes versatile and convenient reactions of boron-substituted heteroaromatic compounds for synthetic heterocyclic chemistry.
