Abstract:
cis-1, 2-Dipheny l-1, 2-dithiohydr oxy ethy lenes, cis-1-pheny-1-2( 4-dimethylamino ) pheny 1-1, 2-dithio hy dro xy ethy lene and their chelates with nickle hav e been synthesized fr om benzoin and 4-dimethy lamino benzoin respect iv ely , these chelates have Kmax betw een 800~100 nm, w hich could be used as disc dy e composit ion w ith He-Ne laser, the effect of the pH value of the react ion medium and the molar ratio of benzoin to P2S5 o n the yield of chelates have been invest igated, as a result the yield of pure chelates co uld be increased hig her than 1. 5% .
