"(2-Butyl)triphenylphosphonium Bromide" is a chemical compound that belongs to the class of organophosphorus compounds. It is most commonly represented by the molecular formula C21H22BrP. This substance is known for its applications in organic chemistry, specifically in the field of synthetic chemistry. The compound is commonly used in the synthesis of more complex molecules due to its ability to act as a strong nucleophile and a reducing agent. It's also used in different reaction types including Wittig reactions, which are often employed in the construction of carbon-carbon double bonds. Despite its utility, care should be taken while handling this substance as it causes serious eye irritation.
Check Digit Verification of cas no
The CAS Registry Mumber 3968-92-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,6 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3968-92:
(6*3)+(5*9)+(4*6)+(3*8)+(2*9)+(1*2)=131
131 % 10 = 1
So 3968-92-1 is a valid CAS Registry Number.

Studies on the intramolecular electron transfer catalyzed thermolysis of 1,2-dioxetanes
Nery, Ana L. P.,Wei?, Dieter,Catalani, Luiz H.,Baader, Wilhelm J.
, p. 5317 - 5327 (2007/10/03)
This work reports the synthesis and the chemiluminescence properties of the dioxetanes: 4-ethyl-4-methyl-3-(3-methoxyphenyl)-1,2-dioxetane (I), 4-ethyl-4-methyl-3-(3-tert-butyldimethylsilyloxyphenyl)-1,2-dioxetane (II), 4,4-dimethyl-3-(3-methoxybenzyl)-1,2-dioxetane (III) and 4,4-dimethyl-3-(3-tert-butyldimethylsilyloxybenzyl)-1,2-dioxetane (IV). While in the thermal decomposition of I-IV preferential formation of triplet excited states is observed, in the presence of fluoride ions the decomposition rate constants of II and IV increase drastically and singlet excited states are formed with high quantum yields. These results are discussed based on the CIEEL ('Chemically Initiated Electron Exchange Luminescence') mechanism where the decomposition of the dioxetanes should be initiated by an intramolecular electron transfer from the phenolate ion (generated by fluoride catalyzed deprotection of the silyloxy group), either directly bound to the peroxidic ring (II) or separated from it by a methylene bridge (IV).
