(α-4-methylbenzoylethylidene)triphenylphosphorane is a complex organic compound with the molecular formula C30H25OP. It is a phosphorus-containing molecule, specifically a phosphorane, which is characterized by the presence of a phosphorus atom bonded to a carbonyl group. (α-4-methylbenzoylethylidene)triphenylphosphorane features a 4-methylbenzoylethylidene group, which is a derivative of acetophenone with a methyl group attached to the benzene ring, and a triphenylphosphorane moiety, which consists of three phenyl groups attached to a phosphorus atom. The structure of (α-4-methylbenzoylethylidene)triphenylphosphorane is significant in organic chemistry, as it can participate in various reactions, such as the Wittig reaction, where it acts as a reagent to form alkenes from aldehydes or ketones. The compound's stability and reactivity are influenced by the electron-donating nature of the methyl group and the electron-withdrawing effect of the carbonyl group, making it a useful intermediate in the synthesis of a variety of organic molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 1450-08-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,5 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1450-08:
(6*1)+(5*4)+(4*5)+(3*0)+(2*0)+(1*8)=54
54 % 10 = 4
So 1450-08-4 is a valid CAS Registry Number.

Transition-Metal-Free Reductive Deoxygenative Olefination with CO2

Zhu, Dao-Yong,Li, Wen-Duo,Yang, Ce,Chen, Jie,Xia, Ji-Bao

supporting information, p. 3282 - 3285 (2018/06/11)

A new transition-metal-free reductive deoxygenative olefination of phosphorus ylides with CO2, an abundant and sustainable C1 chemical feedstock, is described. This catalytic CO2 fixation afforded β-unsubstituted acrylates and vinyl ketones in good yields with broad scope and good functional group tolerance under mild reaction conditions. Cost-effective and easily handled polymethylhydrosiloxane was used as a reductant. Bis(silyl)acetal was proved to be the key intermediate in this reductive functionalization of CO2.

Organocatalytic Redox Isomerization of Electron-Deficient Allylic Alcohols: Synthesis of 1,4-Ketoaldehydes

Mondal, Keshab,Mondal, Buddhadeb,Pan, Subhas Chandra

, p. 4835 - 4840 (2016/07/06)

An organocatalytic redox isomerization strategy has been developed for the synthesis of 1,4-ketoaldehydes. DABCO was found to be the best catalyst for the isomerization of -hydroxy enones. With 20 mol % of DABCO as catalyst and DMSO as the solvent high yi

CONVENIENT PREPARATION OF UNSYMMETRICALLY SUBSTITUTED BENZILS BY PERMANGANATE OXIDATION OF β-OXO PHOSPHORUS YLIDES

Aitken, R. Alan,Cadogan, J. I. G.,Gosney, Ian

, p. 281 - 286 (2007/10/02)

Oxidative cleavage of a range of ylides 4 with R1 and/or R2 being aromatic groups, using KMnO4 in a two-phase system, affords unsymmetrical benzils and 1-arylpropane-1,2-diones 5 in moderate to good yield, and the ylide formation and oxidation can be combined in a convenient one-pot method.Key words: Phosphorus ylides, oxidation, 1,2-diketones, benzils, permanganate, oxoalkylidenetriphenylphosphoranes.
