Dimethyl (2E)-2-[2-oxo-2-phenyl-1-(triphenyl-λ5-phosphanylidene)ethyl]but-2-enedioate is a complex organic compound with the molecular formula C35H29O5P. It is characterized by a conjugated diene system with a phosphorus atom in a λ5-phosphanylidene configuration, which is a unique type of bonding where the phosphorus atom forms five sigma bonds. The molecule features a 2-oxo-2-phenyl-1-(triphenyl-λ5-phosphanylidene)ethyl group attached to a but-2-enedioate moiety, which is a derivative of butenedioic acid (also known as maleic acid). dimethyl (2E)-2-[2-oxo-2-phenyl-1-(triphenyl-lambda~5~-phosphanylidene)ethyl]but-2-enedioate is likely to be of interest in the field of organic chemistry, particularly in the study of phosphorus-containing compounds and their potential applications in materials science or as intermediates in the synthesis of more complex molecules.

7514-61-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7514-61-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,1 and 4 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7514-61:
(6*7)+(5*5)+(4*1)+(3*4)+(2*6)+(1*1)=96
96 % 10 = 6
So 7514-61-6 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.
