, p. 761 - 766 (2015)
A new and efficient method for the synthesis of 2-vinylanilines from the reaction of arylhydrazine hydrochlorides with alkenes and diethyl ketone via a rhodium-catalyzed C-H activation is described. The oxidant-free olefination reaction involves the in situ generation of an -N-N=CR1R2 moiety as the oxidizing directing group thus providing an easy access to 2-vinylanilines.

Although 3-azoindoles have recently emerged as an appealing family of photoswitch molecules, the synthesis of such compounds has been poorly covered in the literature. Herein a high-yielding and operationally simple protocol is reported allowing the synthesis of 3-azoindoles, featuring important steric hindrance around the azo motif. Remarkably, this C-H coupling is characterized by excellent atom economy and occurs under metal-free conditions, at room temperature, and within few minutes, delivering the expected products in excellent yields (quantitatively in most of the cases). Accordingly, a library of new molecules, with potential applications as photochromic compounds, is prepared.
An electroluminescen compound and an electroluminescent device comprising the same
-
Paragraph 0390-0394, (2021/02/02)
The present invention relates to an organic light-emitting compound represented by chemical formula 1. An organic electroluminescent device comprising the organic light-emitting compound in the present invention has excellent power efficiency, light-emitting efficiency, and long life cycle because the present invention can be operated by a lower driving-voltage in comparison with a device comprising conventional phosphorescent host materials.
