Peroxides as "switches" of dialkyl H-phosphonate: Two mild and metal-free methods for preparation of 2-acylbenzothiazoles and dialkyl benzothiazol-2-ylphosphonates
Two mild and metal-free methods for the preparation of two kinds of important benzothiazole derivatives, 2-acylbenzothiazoles and dialkyl benzothiazol-2-ylphosphonates, respectively, were developed. The dialkyl H-phosphonate (RO)2P(O)H exists i
1,3-vs- 1,5-DIPOLAR REACTIVITY OF 1-PHENYLMETHYL-4N-ACETYLIMINO-1H-1,2,4-TRIAZOLIUM BETAIN TOWARD AROMATIC ISOTHIOCYANATES
The title betain I was found to display both 1,3- and 1,5-dipolar reactivity, depending on reaction conditions.Whereas the reaction with aromatic isothiocyanates in nonpolar solvents produced cycloadducts in concerted manner stepwise addition in dimethylf
