Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, 4020-99-9, the author is Fernandez-Garcia and a compound is mentioned, 4020-99-9, Methoxydiphenylphosphine, introducing its new discovery.
Reactions of [1,2-bis(diphenylphosphinite)ethane]bromotricarbonylrhenium(I) with phosphites, phosphonites and phosphinites. The crystal structure of [ReBr(CO)2{Ph2PO(CH2)2 OPPh2}L?] [L? = P(OCH3)3, P(OC2H5)3 and PPh(OC2H5)2]
The rhenium carbonyl complexes cis,mer-[ReBr(CO)2(L)(L?)] [L = 1,2-bis(diphenylphosphinite)ethane, L? = P(OMe)3 (1), P(OEt)3 (2), PPh(OMe)2 (3), PPh(OEt)2 (4), PPh2(OMe) (5), PPh2(OEt) (6)] were synthesised by reaction of [ReBr(CO)3L] with 1 equiv. of the appropriate phosphite, phosphonite or phosphinite. The coordination geometry has been established by NMR, IR and, for compounds 1, 2 and 4, X-ray crystallography. These compounds consist of slightly distorted octahedral monomers. The conformation of the seven-membered ReP2O2C2 chelate ring is a twist-chair for compound 1 and a twist-boat for compounds 2 and 4.
But sometimes, even after several years of basic chemistry education,, 4020-99-9 it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 4020-99-9!
