51451-20-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 51451-20-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,4,5 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 51451-20:
(7*5)+(6*1)+(5*4)+(4*5)+(3*1)+(2*2)+(1*0)=88
88 % 10 = 8
So 51451-20-8 is a valid CAS Registry Number.

Direct Observation of Ultrafast Decarboxylation of Acyloxy Radicals via Photoinduced Electron Transfer in Carboxylate Ion Pairs

Bockman, T. Michael,Hubig, Stephan M.,Kochi, Jay K.

, p. 2210 - 2221 (1997)

Charge-transfer (CT) photoactivation of the electron donor-acceptor salts of methylviologen (MV2+) with carboxylate donors (RCO2-) including benzilates [Ar2C(OH)CO2-] and arylacetates (ArCH2CO2-) leads to transient [MV.+, RCO2.] radical pairs. Femtosecond time-resolved spectroscopy reveals that the photogenerated acyloxy radicals (RCO2.) rapidly lose carbon dioxide by C-CO2 bond cleavage, in competition with back-electron transfer to restore the original ion pair, [MV2+, RCO2-]. The decarboxylation rate constants for ArCH2CO2. lie in the range (1-2) × 109 s-1, in agreement with previous reports. In striking contrast, the C-CO2 bond scission in Ar2C(OH)CO2. occurs within a few picoseconds (kCC = (2-8) × 1011 s-1). The rate constants for decarboxylation of these donors approach those of barrier-free unimolecular reactions. Thus, real-time monitoring of the decarboxylation of benziloxy radicals represents the means for the direct observation of the transition state for C-C bond scission.
