Mol. iodine catalyzed benzylic sp3 C-H bond amination has been developed for the synthesis of quinazolines I (R = H, Ph; R1 = H, 6-Cl, 6,8-Br2; R2 = 4-chlorophenyl, pyridin-3-yl, furan-2-yl, etc.) from 2-aminobenzaldehydes such as 2-amino-5-chlorobenzaldehyde, 2-aminobenzaldehyde, 2-amino-3,5-dibromobenzaldehyde and 2-aminobenzophenones such as 2-aminobenzophenone, 2-amino-5-chlorobenzophenone with benzylamines RCH2NH2. The use of oxygen as a green oxidant combined with the transition-metal-, additive- and solvent-free conditions makes the methodol. economical and greener. The lack of aqueous work up also enhances the efficiency of this protocol. A series of 2-arylquinazolines I was synthesized in good to excellent yields by using the developed protocol. The series of 2-aminobenzyl alc. could also be employed to prepare the corresponding quinazoline derivatives
