Regioselective Thiocyanation of Aromatic and Heteroaromatic Compounds by Using Boron Sulfonic Acid as a New, Efficient, and Cheap Catalyst in Water

Scheme 2

The solvent effect on product yields was investigated using 1a as a substrate. Both the yields and reaction times listed in Table 1 suggest that water appears to be very favorable for thiocyanations in presence of BSA (as a strong and new catalyst).
