Phosphorane, specifically (diphenylmethylene)triphenyl, is a phosphorus-containing compound with the chemical formula C19H15P. It is a colorless, crystalline solid that is highly reactive and sensitive to air and moisture. Phosphorane, (diphenylmethylene)triphenyl- is a phosphorus ylide, which means it has a phosphorus atom with a positive charge and a pair of non-bonding electrons. The structure of (diphenylmethylene)triphenyl-phosphorane consists of a central phosphorus atom bonded to three phenyl groups and a diphenylmethylene group. It is an important reagent in organic chemistry, particularly in the Wittig reaction, where it is used to convert aldehydes and ketones into alkenes. Due to its reactivity, it is typically handled under an inert atmosphere and stored away from light and moisture.

4214-38-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4214-38-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,1 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4214-38:
(6*4)+(5*2)+(4*1)+(3*4)+(2*3)+(1*8)=64
64 % 10 = 4
So 4214-38-4 is a valid CAS Registry Number.

Alkylidenephosphoranes in heterocyclic synthesis: Reactivity of benzoxazinones with resonance-stabilized phosphorus ylides

Kamel, Azza A.,Abdou, Wafaa M.

, p. 1269 - 1273 (2007/12/27)

2H-3,1-Benzoxazine-2,4(1H)-dione and its N-methyl analogue react with alkylidenephosphoranes to give substituted quinolines and benzazepines as well as indanone and furan derivatives. Reaction mechanisms to explain the formation of products obtained are outlined. Georg Thieme Verlag Stuttgart.
