The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.13991-08-7, Name is 1,2-Bis(diphenylphosphino)benzene, molecular formula is C30H24P2. In a Patent£¬once mentioned of 13991-08-7, Safety of 1,2-Bis(diphenylphosphino)benzene
Process for the preparation of urea derivatives and catalyst system
The invention relates to a process for the preparation of urea derivatives of the general formula wherein R is an alkyl group and X is a halogen atom, an alkyl-, alkoxy-, aryloxy-, cyano-, ester- or trifluoromethyl group and n is from 0 to 5,which comprises reacting an aromatic nitro compound of the general formula wherein X and n are as defined above with carbon monoxide and an amine HNR2 wherein R is an alkyl group,in the presence of a catalyst system comprising (a) a group VIII noble metal or a compound thereof, (b) a bidentate ligand and (c) an acid having a pKa of more than 2 or a transition metal salt of said acid.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 13991-08-7 is helpful to your research., Safety of 1,2-Bis(diphenylphosphino)benzene
