β-Bis-CF₃-substituted phosphorus corroles, theory and experiments

Abstract

All constitutional isomers of beta bis-CF3 substituted (tpfc)PF2 were geometrically optimized and studied electronically. The six synthetically accessed compounds were characterized (of the 18 possible) by NMR spectroscopy and other techniques.

Milestones in corrole chemistry: historical ligand syntheses and post-functionalization

“…The 5,10,15-aryl corrole also allows for the addition of a wide variety of b-substituents which may also be electron withdrawing in nature. The presence of the -C 6 F 5 aryl groups can greatly assist in the spectroscopic characterization of new compounds as well (see the recent paper about multi b-CF 3 group substitution 31 ). Milestone: Synthesis of A 3 and ABA corroles (commonly termed trans-A 2 B corroles)…”
