Chemistry involves the study of all things chemical – chemical processes, Application In Synthesis of 1,1′-Ferrocenedicarboxaldehyde, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. In a patent，Which mentioned a new discovery about 1271-48-3
A variety of alkenylcarbene complexes [Cp'(CO)2Mn= C(OEt)CH=CHR] (3) (Cp’ = TiS-MeCsH4) was obtained in a straightforward manner upon aldol condensation of [Cp'(CO)2Mn=C(OEt)CH3] (1) with aromatic and alpha,beta- unsaturated aldehydes RC(H)O (2). The reaction is totally stereoselective, giving (E)- or (all-E)-alkenylcarbenes only. The protonation of 3 at low temperature followed by reaction with water affords the alpha,beta-unsaturated aldehyde complexes [Cp'(CO)2Mn(n2-RCH=CHCHO] (5), from which the aldehydes RC(H)=C(H)C(H)O (6) were displaced by acetonitrile. The intermediate aldehyde complexes are shown to result from the hydrolysis of a transient cationic pi- allyl species [Cp'(CO)2Mn(n3-RCHCHC(OEt)H]+ ([4]+) formed upon protonation of 3.
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis. We will look forword to the important role of 1271-48-3, and how the biochemistry of the body works.Application In Synthesis of 1,1′-Ferrocenedicarboxaldehyde
