Synthesis Reference(s)

Organic Syntheses, Coll. Vol. 3, p. 351, 1955The Journal of Organic Chemistry, 60, p. 4725, 1995 DOI: 10.1021/jo00120a013

Check Digit Verification of cas no

The CAS Registry Mumber 883-40-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,8 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 883-40:
(5*8)+(4*8)+(3*3)+(2*4)+(1*0)=89
89 % 10 = 9
So 883-40-9 is a valid CAS Registry Number.

Spectroscopic and Kinetic Characterization of Diphenyldiazomethane Radical Anion

Chateauneuf, John. E.

, p. 7177 - 7180 (1990)

Diphenyldiazomethane radical anion (Ph2CN2.-) has been generated by radiolytic reduction of diphenyldiazomethane (Ph2CN2) in both protic and aprotic solvents.The absolute kinetics of formation and reactivity of Ph2CN2.- were obtained by monitoring its transient absorption (λmax = 355-370 nm) following nanosecond pulse radiolysis.In isopropylalcohol, reaction of the solvated electron with Ph2CN2 forms Ph2CN2.- (λmax =355 nm), which subsequently protonates to form Ph2C.N2H), as detected by a sharp absorption band at 330 nm.In aprotic solvents and in the ab sence of added quenchers, Ph2CN2.- decays primarily by pseudo-first-order reaction with Ph2CN2.With added weak organic acids protonation of Ph2CN2.- also occurs.Ph2CN2.- reacts with molecular oxygen with a near diffusion-controlled rate; however, it demonstrates no reactivity toward hydrogen atom donors, and no evidence of thermal loss of N2 to produce diphenylcarbene radical anion was observed.
