Synthesis and properties of copper and cobalt phthalocyanine complexes fused with the nitrogen heterocyclic quinones
摘要:
Copper and cobalt complexes of tetra[4,5]([8,9](benzo[f]quinoline-7,10-dione)phthalocyanine, tetra[4,5]-([6,7]1-acetyl-2H-naphtho[2,3-d][1,2,3]triazole-5,8-dione) phthalocyanine, and tetra[4,5]([6,7]3-methylquinoline-5,8-dione)phthalocyanine were synthesized and their spectral properties were investigated.
A new class of herbicidal compounds consisting of 1-alkyl- and 1,1-dialkyl-3-(4-substituted-3-amino-5-isothiazolyl)ureas and N-(4-substituted-3-amino-5-isothiazolyl)-alkanamides, in which the 4-substituent consists of cyano and carbamoyl, exhibits preemergence and postemergence herbicidal activity, controlling effectively the growth of a wide spectrum of grassy and broad-leaved plant species. The synthesis of members of this class is described in detail, and the utility of representative compounds is exemplified.
A process for the manufacture of o-benzyltoluenes by reaction of o-xylyl halides with benzenes in the presence of sulfuric acid or in the presence of phosphoric acid and adjuvants or in the presence of sulfuric acid and adjuvants. The products are starting materials for the manufacture of anthracene and anthraquinone and their derivatives.

The novel compound (3-nitro-4-methyl)-phenyl chloroformate is prepared by reacting (4-methyl)-phenyl chloroformate with nitric acid in the presence of sulfuric acid. The novel compound (3-nitro-4-methyl)-phenyl chloroformate is a valuable starting material for the preparation of dyes and crop protection agents and in particular is an intermediate for the preparation of 3-nitro-4-methylphenol, which is reduced to 3-amino-4-methylphenol.
