2,1-Bensoidoxazoles [anthranils]. Synthesis and opening of the isoxazole ring (review)
The present review covers the literature on the synthesis of 2,l-benzoisoxazoles (anthranils) (I), and reactions of this bicyclic system which involve opening of the isoxazole ring. Since a detailed and satisfactorily full review of the chemistry of 2, l-benzoisoxazoles was published in 1967 [96], the main thrust of the present review is to cover the literature of the last twenty years. It has nevertheless been necessary to include earlier publications, especially when these deal with general methods of synthesis of anthranils. t i. Synthesis of 2~l-Benzisoxazoles
A novel reaction of thionyl chloride with 3-aryl-2,1-benzisoxazoles
Novel reductive chlorination of 3-aryl-2,1-benzisoxazoles with thionyl chloride is described. 
 
 
 
The chlorinated aminobenzophenones have been characterised.
THE IRON-ACETOCARMINE METHOD OF FIXING AND STAINING CHROMOSOMES
A short description of this procedure was given in Vol. 55 of the American Naturalist, pp. 573â€”574. The method has now been used almost daily for five years, and certain improvements have suggested themselves. The solution can be prepared by mixing about equal volumes of glacial acetic acid and water. To this is added powdered carmine in excess. The liquid is then â€ ? just brought to boil, cooled, and decanted. To the red solution there are then added a few drops of a solution of ferric hydrate in 50 per cent. acetic acid, to act as a mordant. The amount of iron varies with different objects. Too much produces a precipitate in a short time. The more
