One of a widely used broad-spectrum industrial bactericidal and mildew prevention agents is 1,2-benzoisothiazolin-3-one (BIT). In present study, it was demonstrated that aerobic oxidative cyclization of 2‑mercaptobenzamide (MBA) and 2,2'-disulfanediyldibenzamide (DSBA) in the presence of Mn(OAc)2 as catalyst allowed to obtain BIT. The mechanism reaction was suggested. It was found that DSBA and MBA can be converted to the BITwith 99% yield at 1.0 mol % Mn(OAc)2 under 0.3 MPa of oxygen and 100°C for 8 h. Experimental data point that this protocol is both economical and environmentally friendly.
