General Description

The chemical compound (2-oxobutyl)(triphenyl)phosphonium, also known as tris(2-oxobutyl)phosphonium, is an organophosphorus compound with the molecular formula C23H24O2P. It is a phosphonium salt that contains a phosphorus atom bonded to three phenyl groups and an (2-oxobutyl) group. (2-oxobutyl)(triphenyl)phosphonium is commonly used as a phase-transfer catalyst in organic synthesis reactions, where it facilitates the transfer of reactants between immiscible phases, such as between an aqueous and an organic phase. It is also used as a stabilizer and flame retardant in polymer materials. The compound's chemical structure and properties make it a versatile and valuable tool in various industrial and research applications.

Check Digit Verification of cas no

The CAS Registry Mumber 19753-61-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,5 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19753-61:
(7*1)+(6*9)+(5*7)+(4*5)+(3*3)+(2*6)+(1*1)=138
138 % 10 = 8
So 19753-61-8 is a valid CAS Registry Number.

Stereochemical studies on the intramolecular imino Diels-Alder reaction

Nader, Bassam,Bailey, Thomas R.,Franck, Richard W.,Weinreb, Steven M.

, p. 7573 - 7580 (2007/10/21)

The intramolecular Diels-Alder cycloaddition of some N-acylimines has been shown to be a totally stereoselective process producing tetrahydropyridine systems having a trans relationship of hydrogens α to nitrogen. Thus, thermolysis of 13 or 14 led to a 55:45 mixture of trans-6,5-fused cycloadducts 16 and 17, respectively. The stereostructures of these compounds were established by direct correlation with authentic methyl dihydropalustramate diastereomers 3,4, and 6. Similarly, precursor 29 cyclized to give exclusively trans-6,5-cyclo adduct 30, whose structure was established by X-ray crystallography on the derived dihydro acid 32. The homologous Diels-Alder precursor 36 also cyclized stereoselectively to give the trans-6,6-fused system 37, which was characterized by X-ray crystallography on acid 38. These stereochemical results have been rationalized on the basis of an azafumarate-type of acylimine intermediate 40 which cyclizes via transition state C, having the N-acyl group endo and the carbomethoxyl group exo.
