(E)-1-(triphenylphosphoranylidene)pent-3-en-2-one is a complex organic compound characterized by a pent-3-en-2-one core structure, which features a carbonyl group at the 2nd position and a double bond between the 3rd and 4th carbon atoms. The molecule is further distinguished by the presence of a triphenylphosphoranylidene group attached to the 1st carbon, which consists of a phosphorus atom bonded to three phenyl rings. This phosphorus-containing group imparts unique reactivity and stability to the molecule, making it a potentially valuable intermediate in organic synthesis and a subject of interest in chemical research. The compound's structure and properties make it suitable for applications in various chemical transformations, particularly those involving phosphorus ylides and the Witting reaction.

6048-13-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6048-13-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,4 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6048-13:
(6*6)+(5*0)+(4*4)+(3*8)+(2*1)+(1*3)=81
81 % 10 = 1
So 6048-13-1 is a valid CAS Registry Number.

Flash Vacuum Pyrolysis of Stabilised Phosphorus Ylides. Part 1. Preparation of Aliphatic and Therminal Alkynes

Aitken, R. Alan,Atherton, J. Ian

, p. 1281 - 1284 (2007/10/02)

Thermal extrusion of Ph3PO from β-oxoalkylidenetriphenylphosphoranes 4 to give the alkynes 5, which under conventional pyrolysis conditions is restricted to cases in which R1 is an electron withdrawing group, has been successfully achieved for R1=H or alkyl by using FVP.The method allows convenient construction of multigram quantities of the alkynes 5 from alkyl halides 1 and allows convenient construction of multigram quantities of the alkynes 5 from alkyl halides 1 and acid chlorides 3 in three steps with good overall yields.Under the conditions used the ylides with R2 = cyclobutyl also undergo less of ethene to provide convenient access to the vinylalkynes 6.
