This invention relates to a novel process for the borylation of arenes and heteroaryls. The present invention also provides novel borenium cations, which act as electrophiles for electrophilic substitution on the arene or heteroaryl ring, as well as to methodology for the preparation of these cations.

A series of ortho-, meta-, and para-boronic acids and their pinacol esters of 1,8-bis(dimethylamino)naphthalene (DMAN), including the very first naphtho[1,8-cd][1,2,6]oxadiborinine-based proton sponge, were synthesized with moderate to good yields. The ease of deborylation of sterically hindered ortho-boronic acids of DMAN was demonstrated. DMAN-based 3,6-diboronic acid and its pinacol ester─valuable

3,2-benzodithiaborole ((CatS2)BCl) are active for arene borylation, displaying reactivity between that of catecholato- and dichloro-boron electrophiles. [(CatS2)B(NEt3)][AlCl4] is significantly less prone to nucleophile-induced transfer of halide from [AlCl4]¯ to boron compared to catecholato and dichloro borocations, enabling it to borylate arenes containing nucleophilic −NMe2 moieties in high conversion
