The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.1608-26-0, Name is Tris(dimethylamino)phosphine
, molecular formula is P[N(CH3)2]3. In a Article，once mentioned of 1608-26-0, name: Tris(dimethylamino)phosphine

Cyclic and acyclic trivalent phosphorus compounds (1, 2, 3, 4) were reacted with activated carbonyl acetylenic compounds as 1-4-diphenyl-2 butyne-1,4-dione; 1-Methoxy-phenyl-4-Phenyl-2-Butyne-1,4-dione; 4-oxo-4-phenyl-Methyl-2-butynoate and 1,3-diphenyl-1-propyne-2-one.All these reaction were performed in presence of protic trapping reagents ZH such as methanol a, phenol b or phtalimid c.All these reactions lead to a very unstable 1,3 dipolar species like which is not detected even at low temperature.This species is protonated instantaneously with the protic trapping reagent ZH giving the following intermediate .Further, Z- may attack the phosphorus atom with formation of a vinylic phosphorane: compounds series A and C, or Z- may attack the electrophilic center of the keto group leading either to ylid formation i.e. compounds serie B or to spirophosphoranes formation i.e. compounds serie D.Mechanisms involved in these reactions are studied.
