71098-90-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 71098-90-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,9 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 71098-90:
(7*7)+(6*1)+(5*0)+(4*9)+(3*8)+(2*9)+(1*0)=133
133 % 10 = 3
So 71098-90-3 is a valid CAS Registry Number.

Electrochemical oxyphenylselenation of dienes

Vukicevic, Rastko D.,Radovic, Milos,Konstantinovic, Stanimir

, p. 1309 - 1312 (2007/10/03)

The electrochemical oxidation of diphenyl diselenide in the presence of dienes affords the corresponding cyclic β-phenylselenoethers via an oxyphenylselenation process. The yields of ethers depend on the nature of the diene and on the reaction temperature

PHENYLSELENENYL CHLORIDE AS A REAGENT FOR THE FACILE PREPARATION OF CYCLIC ETHERS FROM DIOLEFINS

Uemura, Sakae,Toshimitsu, Akio,Aoai, Toshiaki,Okano, Masaya

, p. 1533 - 1536 (2007/10/02)

Various cyclic ethers are prepared in good to excellent yields by treating diolefins with phenylselenenyl chloride in aqueous acetonitrile.This is the most facile method for organoselenium-induced formation of cyclic ethers from diolefins so far reported.

Oxidation of Selenides and Tellurides with Positive Halogenating Species

Detty, Michael R.

, p. 274 - 279 (2007/10/02)

Treatment of diaryl or alkyl aryl selenides and diaryl or dialkyl tellurides first with a positive halogen source (N-chlorosuccinimide, tert-butyl hypochlorite) followed by alkaline hydrolysis (10percent sodium hydroxide, saturated sodium bicarbonate) gave the corresponding selenoxides or telluroxides (or hydrates) in good yield.The method is tolerant of a variety of functional groups including esters, olefins, alcohols, ethers, and ketones.The formal oxidation step is believed to be the formation of a chloroselenonium or chlorotelluronium species followed by hydrolysis. 1H NMR evidence is given for a benzylphenylselenonium species. Selenoxide fragmentation reactions during the hydrolysis step were observed
