Tolyl계 Chloro 화합물에 관한 연구

Studies on Chlorinated Tolyl Compounds.

P, P'-Hexachiorobitolyl, p, p-hexachlorobitolylketone and p, p' hexachlorobitolylthiourea were synthesized by the radical chlorination method of Hass and McBeer. Among these comppounds, l wormicidal activity of p.p'-hexachlorobitolythiourea was much most potent against Clonorchis sinensis than Hetol in vitro. In the process of the p, p'-biolyl chlorination, ${\alpha, \alpha, \alpha}$-trichlorobitolyl was not detected, but small amount of ${\alpha, \alpha, \alpha}$-dichlorobitolyl was detected. This compound was immediately converted bitolyl compounds were analyzed, linear relationship was observed between retention indices and number of chlorine in two series of odd and even numbered chlorine compounds.
