Participants

Reaction Steps

This yellow compound was prepared in a process analogous to the synthesis of PBP in which 2 equivalents of t-butyllithium were used for each equivalent of bathophenanthroline. The clean product was obtained after running chromatography in a silica/mixture of methanol/CH2Cl2 (1:1) column with a yield of 70 percent. 1H NMR (500 MHz, CDCl3) ppm: 9.28 (m, 1H), 7.81-7.74 (m, 2H), 7.68 (s, 1H), 7.57-7.35 (m, 11H), 1.62 (s, 9H). Analysis for mono-t-BBP. Found: C, 86.19, H, 6.18, N, 7.19. Calculated: C, 86.56, H, 6.25, N, 7.21.
