Abstract

Abstract

En 中文
• High-yielding, catalyst- and solvent- free SNAr affords a series of aminobenzophenones • The scalable, green protocol exhibits high atom economy and low E-factors • Selective mono-SNAr of difluorobenzophenones gives novel fluoro-aminobenzophenones • Sequential SNAr efficiently yields novel unsymmetrical bis(cyclic amino)benzophenones • High-yielding Suzuki-Miyaura coupling gives extended bi- and ter-phenyl derivatives
Keywords:
