Related Products of 1038-95-5, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.1038-95-5, Name is Tri-p-tolylphosphine, molecular formula is C21H21P. In a patent, introducing its new discovery.
The acetoxy(phenyl)carbene complex [Cp(CO)2Mn=C(OAc)Ph] (2) reacts with chiral beta-aminoalcohols HOR* [HOR* = N,N-dimethyl alaninol (3), N,N-dimethyl valinol (4), N,N-dimethyl leucinol (5), N,N-dimethylphenyl alaninol (6), and N-formylprolinol (7)] by displacement of the acetoxy substituent and formation of the beta-aminoalkoxy(phenyl)carbene complexes [Cp(CO)2Mn=C(OR*)Ph] (8-12). Irradiation of 9-12 in the presence of PR3 (R = Ph, OMe) affords the carbene(carbonyl)cyclopentadienyl(PR3)manganese complexes [Cp(CO)(PR3)Mn=C(OR*)Ph]. The substitution proceeds diastereoselectively, the diastereomeric excess ranging from 28% to > 90%. The highest diastereoselectivity (> 90%) is observed in the reaction of 9 (R* = CH2C(NMe2)HCMe2H) with PR3. In solution, complex 9 is not stable configurationally and epimerizes within a few days. The reaction of 2 with HOC2H4SCH2Ph affords [Cp(CO)2Mn=C(OC2H4SCH2Ph)Ph] (22) which, on photolysis, is transformed, by loss of a CO ligand, into a chelating carbene complex (24). In the presence of PR3 compound 24 cannot be converted thermally into [Cp(CO)(PR3)Mn=C(OC2H4SCH2Ph)Ph].
