Dimethyl 2-(2-oxo-2-phenylethylidene)-3-(triphenyl-λ5-phosphanylidene)butanedioate is a complex organic compound with the molecular formula C35H31O4P. It is characterized by a butanedioate backbone, with two methyl groups attached to the central carbon atom. The molecule features a 2-oxo-2-phenylethylidene group, which is a phenyl-substituted acetylide, and a triphenyl-λ5-phosphanylidene group, indicating the presence of a phosphorus atom bonded to three phenyl rings in a pentavalent configuration. dimethyl 2-(2-oxo-2-phenylethylidene)-3-(triphenyl-lambda~5~-phosphanylidene)butanedioate is likely to be of interest in the field of organic chemistry, particularly in the synthesis of complex molecules and the study of phosphorus-containing compounds. Its structure and properties make it a potential candidate for applications in materials science, pharmaceuticals, or as a precursor in the synthesis of other organic compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 3448-36-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,4 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3448-36:
(6*3)+(5*4)+(4*4)+(3*8)+(2*3)+(1*6)=90
90 % 10 = 0
So 3448-36-0 is a valid CAS Registry Number.

REACTION OF KETOPHOSPHONIUM YLIDES WITH DIMETHYL ACETYLENEDICARBOXYLATE

Ruder, Suzanne M.

, p. 53 - 58 (2007/10/02)

The reaction of ketophosphonium ylides with dimethyl acetylenedicarboxylate in aprotic solvents gave mixtures of Z and E alkene products.Under protic conditions the initial Michael adduct was protonated and gave Z and E isomers of the alkene product as well.Depending on the alkyl group of the ketoylide, different product ratios were seen.Key words: Ketophosphonium ylide, dimethyl acetylenedicarboxylate, rearrangement, Michael addition.
