Amide derivatives of DMABN: A new class of dual fluorescent compounds
Braun,Rettig,Delmond,Letard,Lapouyade
, p. 6836 - 6841 (1997)
Derivatives of DMABN are described, where the cyano group is replaced by an amide function with different acceptor strengths. This leads to a consistent variation of the dual fluorescence observed, describable within the established TICT model. Time resolved experiments give evidence of an additional complication with respect to DMABN due to the low-lying nπ* state of the amides which induces a fluorescence quenching channel. The presence of various conformers leads to the observed nonexponential fluorescence decay traces.

Present work reports the direct synthesis of amides from oxidative coupling of benzyl alcohols with various N-substituted formamides using a cobalt-hydrotalcite (Co-HT) derived catalyst. The Co-HT derived catalysts (Co-HT-2, Co-HT-3 and Co-HT-4 having Co2+/Al3+ molar ratio in the catalyst preparation mixture as 1/1, 2/1 and 3/1 respectively) were prepare following a co-precipitation method and characterized well by powder XRD, XPS, FEG-SEM, EDS, DTG–TGA, FT-IR and N2 physisorption measurements. A range of functional amides were obtained in good yields from oxidative coupling of various substituted benzyl alcohols and a range of N-substituted formamides using Co-HT-3 catalyst and oxidant TBHP. Mechanistic investigation suggests that the amidation reaction is associated with the formation and coupling of radical species. Furthermore, the Co-HT derived catalyst was easily recoverable and recyclable with retained high catalytic activity towards the oxidative coupling of benzyl alcohol with DMF.
