Tetrakis(dimethylamino)ethylene (TDAE) mediated addition of difluoromethyl anions to heteroaryl thiocyanates. A new simple access to heteroaryl–SCF2R derivatives
摘要:
New heteroaryl-SCF2R derivatives 8-13 are easily obtained in one-pot from the tetrakis(dimethylamino)ethylene (TDAE) mediated reduction of halogenodifluoromethyl substrates RCF2X 1-4 in the presence of heteroaryl-thiocyanates 5-7. (C) 2001 Elsevier Science Ltd. All rights reserved.
