A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 50777-76-9, Name is 2-(Diphenylphosphino)benzaldehyde, molecular formula is C19H15OP. In a Article，once mentioned of 50777-76-9, HPLC of Formula: C19H15OP
Following the method of Prato et al., reaction of C60, N-methylglycine and o-(diphenylphosphino)benzaldehyde affords PPh 2(o-C6H4)(CH2NMeCH)C60 (1) in moderate yield. Compound 1 reacts with W(CO)4(NCMe) 2 to produce W(CO)4(eta3-PPh 2(o-C6H4)(CH2NMeCH)C60) (2), through coordination of the phosphine group and one 6:6-ring junction of fullerene. Reaction of 1 and Os3(CO)11(NCMe) affords Os3(CO)11(PPh2(o-C6H 4)(CH2NMeCH)C60) (3), which undergoes a cluster fragmentation reaction in refluxing toluene to produce Os(CO) 3(eta3-PPh2(o-C6H 4)(CH2NMeCH)C60) (4). Thermal reaction of 1 and Os3(CO)12 affords 3 and 4. On the other hand, reaction of 1 and Ru3(CO)12 yields only the mononuclear complex Ru(CO)3(eta3-PPh2(o-C6H 4)(CH2NMeCH)C60) (5). The structures of 1-3 and 5 were determined by an X-ray diffraction study.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.HPLC of Formula: C19H15OP, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 50777-76-9, in my other articles.
