Two series of novel 1,2,3-benzotriazin-4-one derivatives containing thiourea and acylthiourea were designed and synthesized. The bioassay results showed that most of the test compounds showed good nematicidal activity against M. incognita at the concentration of 10.0?mg?L?1 in vivo. The compounds A13, A17 and B3 showed excellent nematicidal activity on the second stage juveniles of the root-knot nematode with the inhibition rate of 51.3%, 58.3% and 51.3% at the concentration of 1.0?mg?L?1 respectively. It suggested that the structure of 1,2,3-benzotriazin-4-one derivatives containing thiourea and acylthiourea could be optimized further.

A facile and efficient synthesis of isothiocyanates from amines is described. This method involves the reaction of amines with phenyl chlorothionoformate in the presence of solid sodium hydroxide by either a one-pot process or a two-step approach. The one-pot process is useful for preparing alkyl and electron-rich aryl isothiocyanates, whereas the two-step approach is more versatile, working very well not only for alkyl and electron-rich aryl isothiocyanates, but also for highly electron-deficient aryl and heterocyclic isothiocyanates.

2-Imino-1,3-thiazetidines and 2-imino-1,3-dithietanes were synthesized and their reactivities were studied.The former readily underwent ring-opening reaction with amines to yield guanidine derivatives.The reaction products were applied to the synthesis of heterocycles such as triazoles and triazines.The latter was converted to isothiocyanate by the reaction of m-chloroperbenzoic acid.
