Phototriggered Dehydration Condensation Using an Aminocyclopropenone
摘要:
A phototriggered dehydration condensation using an aminocyclopropenone has been developed. The UV irradiation of an, aminocyclopropenone generated a highly reactive ynamine in situ and the dehydration condensation of a carboxylic acid and an amine coexisting in the reaction solution smoothly proceeded to afford an amide. This reaction is completely controllable by the ON/OFF states of a UV lamp.

We have described an efficient method for oxidative cross coupling reactions between activated N–H amines and terminal alkynes using heterogeneous Cu2(BDC)2(BPY) as recyclable catalyst (BDC = benzene-1,4-dicarboxylate; BPY = 4,4′-bipyridine).
In an organic EL device, a light emitting layer contains a specific coumarin derivative, and a hole injecting and/or transporting layer contains a specific tetraaryldiamine derivative. Also a light emitting layer in the form of a mix layer contains a specific coumarin derivative, a specific quinacridone compound or a specific styryl amine compound. There are provided at least two light emitting layers including a light emitting layer of the mix layer type wherein at least two dopants are contained so that at least two luminescent species may emit light. There is obtained an organic EL device capable of high luminance and continuous light emission and ensuring reliability. Multi-color light emission becomes possible.
