The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.1038-95-5, Name is Tri-p-tolylphosphine, molecular formula is C21H21P. In a Article，once mentioned of 1038-95-5, Computed Properties of C21H21P

Protonation of the trinuclear anionic rhenium cluster [HNEt3][Re3(mu- H)3(mu3-ampy)(CO)9] (1) (Hampy = 2-amino-6-methylpyridine) with [HOEt2][BF4] at low temperature leads to dihydrogen and the neutral unsaturated dihydride derivative [Re3(mu-H)2(mu3-ampy)(CO)9]. The low thermal stability of this compound (it undergoes decomposition above 5 C) has prevented its isolation as a pure solid. The compound [Re3(mu- H)3(CO)12] is the major product obtained when the protonation of 1 is carried out under CO. Protonation of 1 in the presence of phosphanes or alkynes gives the neutral derivatives [Re3(mu-H)2(mu3-ampy)(PR3)(CO)9] (2: R = Ph; 3: R = p-to-lyl) or [Re3(mu3-H)(mu3-ampy)(mu-RC=CHR’)(CO)9] (4: R = R’ = Ph; 5: R = R’ =Et; 6a: R = Ph, R’ = H; 6b: R = H, R’ = Ph). In 2 and 3, the phosphane ligand is in an equatorial position on an Re atom of the NH-bridged Re-Re edge, cis to a hydride ligand and far away from the other hydride ion. In compounds 4-6, the alkenyl ligand, which arises from the insertion of the corresponding alkyne into an Re-H bond, is attached to two metal atoms in a mu-eta1:eta2 fashion, spanning the same Re-Re edge as the NH fragment of the ampy ligand. The hydride ligand of compounds 4-6 coordinates in a triply bridging fashion, capping the Re3 triangle. Compounds 4-6 represent the first examples of trirhenium clusters containing alkenyl ligands.
