摘要:
WHERE R and R'' are hydrogen, hydroxy, lower alkoxy or halogen; R'''' is lower alkyl, lower alkoxy, halogen, nitro or trihalomethyl; x is 0 or a positive integer from 1 to 4 and R1, R2, and R3 are lower alkyl, with the proviso that when R and R'' are both hydrogen, x is a positive integer.
A new series of 2-(poly substituted phenyl)-1,3-indandione compounds have been found to have exceptional miticidal and herbicidal activity. These compounds may be represented by the following general formula:

Process for the preparation of carbocylic indenones of the formula (1)
WHERE R1 through R6 are as defined above, with acetoacetyl fluoride in at least 90 % hydrofluoric acid at temperatures of from -10* to +120*C, optionally after a 2 hours residence time of the reaction mixture in a temperature range of from -20* to 50*C, which is a novel process yielding peri-indenones with substantially higher yields and in higher degree of purity than known processes, or yielding peri-indenones which are not obtained by the known processes.
WHEREIN R1 through R6 each are hydrogen, fluorine, chlorine, nitro, trifluoromethyl, alkyl and/or alkoxy, each having from 1 to 4 carbon atoms, and/or two adjacent radicals each of R1 through R6 together form a single or multiple carbocyclic aromatic ring, or two or more radicals together form a carbocyclic aromatic system, or the radicals R1 and R6 together form the radical of the formula -CH2-CH2-, which comprises reacting carbocyclic aromatic compounds ahving a free peri-group and corresponding to the formula (2)

5-Fluoro-2-methyl-1-(4''-methylsulfinylbenzylidene)-3-indenyl acetic acid is prepared by processes that form the 3-acetic acid side chain as the final step.
摘要:
The known compound, 1,2,3,4,9,9-hexachloro-1,4-dihydro-1,4methanonaphthalene-5,8-diol (I) is an excellent flame retardant for ABS resins and polyurethanes, particularly, polyether-based polyurethanes. Compound I also forms novel molecular complexes with weak bases such as pyridine, pyridine HCl, pyridine oxide, dimethylsulfoxide and dimethylformamide, and which are excellent flame retardants for ABS resins. Compound I also exhibits unusual synergistic flame retardant effects in ABS resins and other polymers when used together with certain additives that are not themselves flame retardants.
