Regioselectivity in the nucleophile trapping of arynes: the electronic and steric effects of nucleophiles and substituents



Regioselectivity in the nucleophile trapping of arynes: the electronic and steric effects of nucleophiles and substituents



Organic Letters 16(1): 6-9



The regioselectivity in nucleophile trapping is investigated with arynes generated directly from bis-1,3-diynes. The regioselectivity is profoundly influenced by not only the nature of nucleophiles but also the substituents on the arynes, which is the consequence of both the unfavorable steric interaction between the incoming nucleophile and the nearby substituent and the inherent electronic bias induced by different substituents on the arynes.
