1038-95-5, Name is Tri-p-tolylphosphine, molecular formula is C21H21P, belongs to chiral-phosphine-ligands compound, is a common compound. In a patnet, once mentioned the new application about 1038-95-5, Safety of Tri-p-tolylphosphine
Treatment of <(eta5-C5H4CH2CH2OH)M(CO)3PR3>+BF4- (1a-d, M = Mo, W; R = Ph, p-tolyl) with base affords solely the neutral intramolecular metalloester, trans-(eta5-C5H4)CH2CH2O2CM(CO)2PR3 (2).The X-ray structure of 2b (M = W; R = Ph) (space group P21/n, a = 8.127 Angstroem, b = 16.823 Angstroem, c = 17.623 Angstroem, beta = 101.980 deg, V = 2357 (1) Angstroem3, Z = 4) was solved by heavy-atom and Fourier methods and refined by full-matrix least squares to S (goodness-of-fit) = 1.27 and R = 0.043 (5728 reflections).The structural results indicate that there is little or no strain upon coordination of the Cp and ester groups when coupled with the ethylene bridge.Equilibrium studies indicate that DeltaH0 and DeltaS0 are -1.1 +/- 0.6 kcal/mol and 3.2 +/- 2.0 eu and -1.9 +/- 0.2 kcal/mol and 4.5 +/- 0.6 eu for 2c (M = Mo; R = p-tolyl) and 2d (M = W; R = p-tolyl), respectively, for the reaction with MeOH in benzene to form the methyl ester and regenerate the alcohol-substituted Cp.Treatment of the analogous compound (1g), in which the alcohol is connected to the Cp by CH2, with methoxide yields an intramolecular metalloester (3) as well.Equilibrium data indicate that the intramolecular metalloester is more stable than the methyl ester, Keq /=230 M-1 (5e) and >/=117 M-1 (5f).
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Safety of Tri-p-tolylphosphine. In my other articles, you can also check out more blogs about 1038-95-5
