Synthesis of enediyne model compounds producing toluene diradicals possessing a highly radical character via enyne–allene intermediates
摘要:
Development of enediyne model compounds that produce dehydrotoluene diradicals under acidic media is described. The ionic character of the diradicals is shown to be avoided by the electron-withdrawing groups in the molecules both in benzene and MeOH. (C) 2000 Elsevier Science Ltd. Ail rights reserved.
