57266-34-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57266-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,2,6 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 57266-34:
(7*5)+(6*7)+(5*2)+(4*6)+(3*6)+(2*3)+(1*4)=139
139 % 10 = 9
So 57266-34-9 is a valid CAS Registry Number.

Unsymmetrical disulfide and sulfenamide synthesis via reactions of thiosulfonates with thiols or amines

Taniguchi, Nobukazu

, p. 2030 - 2035 (2017/03/17)

The reactivity of thiosulfonates with nucleophilic reagents was investigated. When reactions of thiosulfonates with thiols were performed, unsymmetrical disulfides were obtained in excellent yields. This procedure could employ numerous aryl or alkyl thiols. On the other hand, reactions of thiosulfonates with amines proceeded in the presence of a copper catalyst. The procedure was performed efficiently in air, and afforded the corresponding sulfenamides.

Disproportionation reaction of disulfides promoted by nitric oxide (NO) in the presence of oxygen

Itoh, Takashi,Tsutsumi, Nozomi,Ohsawa, Akio

, p. 2161 - 2166 (2007/10/03)

Two disulfides brought about disproportionation reaction to afford an unsymmetrical disulfide in 50% yield with a catalytic amount of nitric oxide in the presence of oxygen. The reaction proceeded faster when alkyl disulfides were employed for the reaction, and the substituent effects suggested that the reaction commenced with an oxidative process.

Some Unusual Properties of Tris(2,6-dimethoxyphenyl)phosphine Sulfide and the Related Compounds

Wada, Masanori,Kanzaki, Mitsuyuki,Fujiwara, Masanobu,Kajihara, Kazuhisa,Erabi, Tatsuo

, p. 1782 - 1786 (2007/10/02)

The title sulfide 3P=S reacted with acids to form a novel mercaptophosphonium salt X, solution thermolysis of which in the absence or presence of triphenylphosphine resulted in the unusual desulfurization to give the tertiary phosphonium salts X. (2,6)3P=S also reacted with alkyl iodides or bromides under mild conditions to give stable (alkylthio)phosphonium salts X (R=Me, Et, n-Bu), which reacted with thiols at room temperature in the presence of a catalytic amount of the tertiary phosphine (2,6)3P to give X and unsymmetrical disulfides.
