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

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

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.
