The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.166330-10-5, Name is (Oxybis(2,1-phenylene))bis(diphenylphosphine), molecular formula is C36H28OP2. In a Article，once mentioned of 166330-10-5, Quality Control of: (Oxybis(2,1-phenylene))bis(diphenylphosphine)
Herein we describe an efficient protocol for the regioselective addition of 1,3-dicarbonyl compounds to internal alkynes catalyzed by rhodium/Lewis acid catalysts. The corresponding branched/linear allylic alkylation products could be selectively obtained in good yields. Rh-H species were considered to be generated by direct C-H oxidative addition of 1,3-dicarbonyl compounds with rhodium catalyst with the assistance of Lewis acid. Moreover, a retro-allylic alkylation process was observed in this transformation.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of: (Oxybis(2,1-phenylene))bis(diphenylphosphine), you can also check out more blogs about166330-10-5
