三氟甲基取代的超亲电体产生的超强酸(CF3SO3H)和他们的化学进行了检查。三氟甲基的强吸电子性质被发现,以提高在超亲电体的阳离子位点的亲电字符。这导致在超亲电体中更大的正电荷离域。这些作用表现为超亲电体在反应中表现出不寻常的化学选择性、区域选择性和立体选择性。
Trifluoromethyl-substituted superelectrophiles were generated in superacid (CF3SO3H) and their chemistry was examined. The strong electron withdrawing properties of the trifluoromethyl group are found to enhance the electrophilic character at cationic sites in superelectrophiles. This leads to greater positive charge-delocalization in the superelectrophiles. These effects are manifested by the superelectrophiles showing unusual chemo-, regio-, and stereoselectivity in reactions.
