Triphenyl(α-phenylcinnamyliden)-phosphoran is a complex organic phosphorus compound with the chemical formula C35H27P. It is characterized by a phosphorus atom bonded to three phenyl groups and a cinnamyliden group, which is derived from the α-phenylcinnamyl moiety. Triphenyl(α-phenylcinnamyliden)-phosphoran is of interest in the field of organophosphorus chemistry due to its unique structure and potential applications in areas such as materials science and pharmaceuticals. The compound's stability, reactivity, and specific properties are influenced by the electron-donating nature of the phenyl groups and the conjugated system present in the cinnamyliden moiety.

Check Digit Verification of cas no

The CAS Registry Mumber 80922-45-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,9,2 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 80922-45:
(7*8)+(6*0)+(5*9)+(4*2)+(3*2)+(2*4)+(1*5)=128
128 % 10 = 8
So 80922-45-8 is a valid CAS Registry Number.

Reactions of Allylidenephosphoranes with Heterocumulenes, II. New Syntheses of 1,2,4-Pentatrienes and 2-Pentene-1,5-diones

Capuano, Lilly,Wamprecht, Christian,Willmes, Arnold

, p. 3904 - 3907 (2007/10/02)

Cinnamylidenetriphenylphosphorane (2a) undergoes Wittig reaction with ketenes to afford monomeric and dimeric 1,2,4-pentatrienes 4 and 5, resp. 4b reacts further with an excess of ketene via a -cycloaddition, whereby the 3-styryl-1-naphthyl diphenylacetate 12 is formed.In contrast, with the α-phenylsubstituted phosphorane 2b, instead of the Wittig reaction addition of ketene takes place at both the α- and the γ-positions.The 1,3-diacyl-3-triphenylphosphonio-1-propen-3-enolate 6 readily hydrolyzes to the 2-pentene-1,5-dione 9.

Capuano, Lilly,Willmes, Arnold

, p. 80 - 86 (2007/10/02)

According to their α-substituent the allylidenephosphoranes 4 are converted by isocyanates either via Wittig reaction into the hitherto little known vinylketenimines 7 or by carbamoylation and ring closure into the pyrrolone 5 or the 3-pyridylidenephospho
