The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.4020-99-9, Name is Methoxydiphenylphosphine, molecular formula is C13H13OP. In a Article，once mentioned of 4020-99-9, Formula: C13H13OP
[ReBr(CO)5] reacted with phosphinite or phosphonite ligands in benzene or toluene to yield fac-(1) or mer,trans-(2) complexes, ([ReBr(CO)3(L)2] L = PPh2(OMe), a; PPh2(OEt), b; PPh(OMe)2, c; PPh(OEt)2, d) characterized by elemental analysis, mass spectrometry, IR and NMR (1H, 13C and 31P) spectroscopies, and for complexes 1b, 2c and 2d, X-ray diffractometry was used. Complexes 2a-2d reacted with Ag[BF4] in wet acetone to form moderate yield of mer,trans-[Re(H2O)(CO)3(L)2][BF4] (3). Comparison of the spectra of compounds 3 with those of precursors 2 together with the diffractometric results for compounds 3a-3c, show that all the complexes have the same configuration around the rhenium atom. Crystals of compounds 3 consist of centrosymmetric dimers formed by hydrogen bonds between the water molecules and the BF4- anions. The lability of compounds 3 was explored by 19F and 31P NMR, and in the case of 3c the complex [Re(nu1-BF4)(CO)3 {PPh(OMe)2}2] (4c) was isolated from the mother liquor. Spectroscopic and diffractometric studies of 4c show monodentate coordination of the tetrafluorborato ligand to the rhenium atom.
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.Formula: C13H13OP, you can also check out more blogs about4020-99-9
