Calculate Digit Verification of CAS Registry Number 87054-07:
(7*8)+(6*7)+(5*0)+(4*5)+(3*4)+(2*0)+(1*7)=137
137 % 10 = 7

Synthesis and reactivity of benzoxa(thia)zol-2-thiones: New route to 2- alkylthiobenzoxa(thia)zoles

Harizi, Abdallah,Romdhane, Anis,Mighri, Zine

, p. 5833 - 5835 (2007/10/03)

The reaction of aromatic primary amines 1 with carbon disulfide in the presence of a catalytic amount of triethylamine followed by treatment with aqueous hydrogen peroxide leads to the corresponding benzoxa-(thia)zol-2- thiones 3a-c which can be transformed with iminoethers into 2- alkylthiobenzoxa(thia)zoles 5a-h in good yields (64-85%).
