    Abstract: PROBLEM TO BE SOLVED: To obtain a new compound useful as an antiseptic disinfectant effective not only for Gram-negative bacteria, Gram-positive bacteria and true fungi but also for sporulating microorganism, acid-fast bacteria such as highly resistant tubercle bacillus, Pseudomonas aeruginosa and viruses. SOLUTION: The objective compound is expressed by formula I or formula II, formula III or formula IV, or formula V or formula VI. The compounds of formulas I to VI are each useful as a disinfectant for wide variety of microorganisms. The disinfectant preferably contains the active component in the form of aqueous and/or alcoholic solution or aqueous emulsion at a effective component concentration of 0.001-50.0wt.%. The compound of formula I or II can be produced by reacting povidone-iodine with benzalkonium chloride, the compound of formula III or formula IV can be produced by reacting an iodine compound with benzalkonium chloride and the compound of formula V or formula VI can be produced by reacting benzylhydrazine hydrochloride with an iodine compound. The disinfectant exhibits disinfection effect even in the presence of an organic materials and is effective even at a high temperature.

    Abstract: PURPOSE:To obtain a 3-halogeno aromatic compound useful as an intermediate for medicines and agrochemicals in high yield while suppressing by-products by subjecting an aromatic compound such as 2-amino-5-trifluoromethylpyridine to specific halogenating reaction, then to rearrangement reaction. CONSTITUTION:An aromatic compound of formula I [X is OH, amino or acylamino; Z1 and Z2 are H, halogen; one of R and Y is H and the other is nitro, cyano or trifluoromethyl; Q is N or C(T)=-(T is H, halogen, nitro, cyano or trifluoromethyl] is reacted with a halogenating agent to give a halogeno aromatic compound of formula II [E is O-Hal or N(A)-Hal (A is H or acryl)], subjecting this compound to rearrangement reaction in the presence of a proton donor to give a 3-halogeno aromatic compound of formula III (one of R' and Y' is halogen and the other is nitro, cyano or trifluoromethyl). This reaction is most suitable for obtaining a 3-halogenopyridine of formula VI especially from a pyridine derivative of formula IV and a halogenating agent through a compound of formula V.
