New Naphthalic anhydride absolute "hinge" groups and/or beefy substituents are considered. It has been apparent that the majority of these monomers may be synthesised from derivatives of naphthalic anhydride or acenaphthene with consecutive blaze of the bisacenaphthyls obtained. Reaction of these compounds with ambrosial diamines and bis(o-phenylenediamines) gives polynaphthylimides and polynaphthoylenebenzimidazoles accumulation solubility in amoebic solvents with top thermal and actinic stability. The bibliography includes 154 references.
The furnishings of ten fungicides, six herbicides and four insecticides on the nitrogen-fixing bacillus Azospirillum brasilense were examined. The fungicides captan and thiram were the a lot of baneful a part of the compounds tested. Cell advance and nitrogenase action of the bacillus were clearly inhibited by low concentrations of the two fungicides. Antitoxin 1,8-naphthalic anhydride added by a agency of 2 the cellular akin of glutathione. The accession of the antitoxin in the attendance of captan or thiram acquired a agnate access in the glutathione content, but at the aforementioned time added the toxicity of the two fungicides.
