49838-80-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 49838-80-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,8,3 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 49838-80:
(7*4)+(6*9)+(5*8)+(4*3)+(3*8)+(2*8)+(1*0)=174
174 % 10 = 4
So 49838-80-4 is a valid CAS Registry Number.

Bi(NO3)3.5H2O: A convenient reagent for selective oxidation of sulfides to sulfoxides

Mashraqui, Sabir H.,Mudaliar, Chandrasekar D.,Karnik, Madhavi A.

, p. 939 - 943 (1998)

Bi(NO3)3.5H2O, a cheaply available, crystalline solid has been found to readily effect selective oxidation of a variety of sulfides to surfoxides in acetic acid medium at room temperature in fair to good yields.

Visible-light-activated selective synthesis of sulfoxides via thiol-ene/oxidation reaction cascade

Singh, Manjula,Yadav, Arvind K.,Yadav, Lal Dhar S.,Singh

, p. 450 - 453 (2018/01/05)

A convenient, highly selective and metal-free synthesis of sulfoxides from alkenes and thiols using NHPI as an inexpensive and reusable organophotoredox catalyst is reported. The protocol involves radical thiol-ene/oxidation reaction cascade and utilizes visible light and air (O2) as inexpensive, readily available, non-toxic and eco-sustainable reagents to afford up to 96% yields of the product at room temperature.

Visible-light-induced selective synthesis of sulfoxides from alkenes and thiols using air as the oxidant

Cui, Huanhuan,Wei, Wei,Yang, Daoshan,Zhang, Yulong,Zhao, Huijuan,Wang, Leilei,Wang, Hua

supporting information, p. 3520 - 3524 (2017/08/15)

A highly selective synthesis of sulfoxides from alkenes and thiols was established by visible-light photoredox catalysis at room temperature. This metal-free transformation protocol, which uses inexpensive Rose Bengal as the photocatalyst and air as the green oxidant, opens a new door toward the facile and practical construction of sulfoxides.

Utilizing sulfoxide???iodine halogen bonding for cocrystallization

Eccles, Kevin S.,Morrison, Robin E.,Stokes, Stephen P.,O'Mahony, Graham E.,Hayes, John A.,Kelly, Dawn M.,O'Boyle, Noel M.,Fabian, Laszlo,Moynihan, Humphrey A.,Maguire, Anita R.,Lawrence, Simon E.

experimental part, p. 2969 - 2977 (2012/08/14)

The propensity of a range of different sulfoxides and sulfones to cocrystallize with either 1,2- or 1,4-diiodotetrafluorobenzene, via I???O=S halogen bonding, was investigated. Cocrystallization occurred exclusively with 1,4-diiodotetrafluorobenzene in ei

Antioxidative properties of phenyl-substituted phenols. Part I. The mechanism of synergism between 4-alkoxy-2,6-diphenylphenols and ββ′-disubstituted diethyl sulphides

De Jonge, Cornelis R. H. I.,Hageman, Hendrik J.,Huysmans, Willem G. B.,Mijs, Willem J.

, p. 1276 - 1279 (2007/10/06)

A pronounced synergism between 4-alkoxy-2,6-diphenylphenols and ββ′-disubstituted diethyl sulphides has been observed in the inhibition of autoxidation of polypropene at 180°C. The mechanism of this synergistic action (at temperatures ≥150°C) has been investigated. N.m.r. model experiments have shown that the phenolic antioxidant (AH) is regenerated continuously from the phenoxyl radical (A·) by hydrogen atom donation by the sulphenic acid, a product originating from the ββ′- disubstituted diethyl sulphide. This observation is of possible contributory importance to the understanding of the mechanism of synergistic effects.
