Direct alkyl sp3 C–H activation to form new C–C bonds is one of the major challenges in synthetic chemistry. Herein, for the first time, we represent a new method, using nano Pd/ZnO which plays both as photoredox and transition-metal catalyst, for C–C bond formations. By using this catalyst, we have accomplished an oxidative coupling reaction between aryl halides and tertiary amines to yield the corresponding naturally occurring alkyl aryl ketones by using visible light irradiation. Furthermore, the carbonylation process was carried out on a 10 gram scale, with visible light and thermal condition, and it was proved to be scalable, efficient, and economical.

, (2008/06/13)
This invention relates to new ethanolamine derivatives having gut selective sympathomimetic and anti-pollakiuria activities and represented by the general formula [I]: STR1 wherein R1 is aryl or a heterocyclic group, each of which may be substituted with halogen, etc., R2 is hydrogen, halogen, nitro, hydroxy, lower alkyl optionally substituted with acyl, lower alkenyl optionally substituted with acyl, lower alkoxy optionally substituted with acyl, or amino optionally substituted with acyl(lower)alkyl, R3 is hydrogen, an N-protective group, or lower alkyl optionally substituted with lower alkylthio, n is an integer of 0 to 3, and a heavy solid line means a single bond or a double bond, provided that when n is 1, then 1) R1 is a condensed aromatic hydrocarbon group or a heterocyclic group, each of which may be substituted with halogen, etc., and the like, and pharmaceutically acceptable salts thereof to processes for the preparation thereof and to a pharmaceutical composition comprising the same.
