A regioselective visible light induced synthesis of aryl α-thiocyano ketones/thiocyano alcohols from activated terminal aryl alkynes and aryl 1,3-conjugated dienes was achieved. This mild and non-metallic oxidation is exclusively driven by benign ambient air in the presence of an organic photo-catalyst and NH4SCN. This protocol was also demonstrated at the 5 mmol scale for the synthesis of potentially therapeutic 2-hydroxy 4-substituted arylthiazoles in good yields, signifying its amenability for large-scale application.

Paragraph 0470; 0471; 0475, (2013/11/18)
The present invention provides a compound having an excellent efficacy for controlling pests. A tetrazolinone compound of a formula (1): [wherein, R1 represents an C6-C16 aryl group, an C1-C12 alkyl group, a C3-C12 cycloalkyl group or an adamantyl group, etc., which each optionally be substituted; R2 represents a hydrogen atom, an C1-C12 alkyl group, or a halogen atom, etc.; R4 and R5 represent independently of each other a hydrogen atom or an C1-C3 alkyl group, etc.; R6, R7, R8 and R9 represent independently of each other a hydrogen atom, a halogen atom, an C1-C12 alkyl group, a C1-C12 haloalkyl group, an C2-C12 alkenyl group, a C3-C12 cycloalkyl group, an C1-C12 alkoxy group or a C1-C12 haloalkoxy group, etc.; X and Y represent independently of each other a sulfur atom or an oxygen atom; Q represents an oxygen atom or a sulfur atom; and R10 represents an C1-C6 alkyl group, etc.] shows an excellent controlling efficacy on pests.

Sixteen 4-arylthiazol-2(3H)-ones (3) were synthesised by cyclisation of α-thiocyanatoacetophenones (1) in acid solution. They appear to prefer greatly the oxo tautomeric forms. In CCI4 solution an equilibrium between the free C=O bond and a "di
