38632-84-7 Usage

Uses

Benzyl Benzenesulfonate is a benzyl arylsulfonate with potential use as a cationic polymerization initiator. Benzyl Benzenesulfonate is also a useful reagent in the preparation of Donepezil (D531750).

Check Digit Verification of cas no

The CAS Registry Mumber 38632-84-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,6,3 and 2 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 38632-84:
(7*3)+(6*8)+(5*6)+(4*3)+(3*2)+(2*8)+(1*4)=137
137 % 10 = 7
So 38632-84-7 is a valid CAS Registry Number.

Photoinduced electron transfer reactions of benzyl phenyl sulfides promoted by 9,10-dicyanoanthracene

Baciocchi, Enrico,Crescenzi, Cristina,Lanzalunga, Osvaldo

, p. 4469 - 4478 (2007/10/03)

The photoinduced oxidation of benzyl phenyl sulfides 1-3 has been investigated in MeCN using 9,10-dicyanoanthracene as sensitizer in the presence of O2. In this reaction a sulfide radical cation is formed, which undergoes one or more of the three main reaction pathways opened to these species: C-S bond cleavage, C-H bond cleavage and S-oxidation. The former route (leading to benzylic products) was observed with all the substrates investigated, whereas the second (leading to benzaldehydes) operates only with 1 and 2. Formation of sulfoxides was found solely in the photooxidation of 1. The influence of substrate structures on the relative contribution of the three pathways as well as the role of O2- in this respect are discussed.
