How an Eight-Membered Ring Alters the Rhodamine Chromophore
摘要:
Readily available phenylene-1,3-diamines can be converted into unprecedented analogues of rhodamine and malachite green possessing a central eight-membered ring in three steps. The overall process couples a cyanine chromophore with a urea bridge giving rise to new dyes possessing distinct spectral characteristics: absorption of orange light combined with a weak emission of red light both in solution and in the crystalline state. Their photophysics is governed by the twist of lateral phenyl rings and intramolecular and intermolecular CT transitions.

procedure for the synthesis of N‐methyl‐arylamines directly from nitroarenes using methanol as green methylating agent was developed. The key to success is the use of a specific catalyst system consisting of palladium acetate and the ligand 1‐[2,6‐bis(isopropyl)phenyl]‐2‐[tert‐butyl(2‐pyridinyl)phosphino]‐1H‐Imidazole (L1). The generality of this protocol is demonstrated in the synthesis of more than 20

A manganese‐catalyzed one‐pot conversion of nitroarenes into N‐methylarylamines has been developed. This transfer hydrogenation method employs a well‐defined bench stable Mn PN3P pincer precatalyst in combination with methanol as both the reductant and the C1 source. A selection of commercially available nitroarenes was converted into N‐methylarylamines in synthetically useful yields.
