摘要:
Cycloalkanones, cycloalkanols and unsaturated analogs thereof, each of which has at the 3-position a 2-hydroxy-4-substituted phenyl group wherein the 4-position substituent is alkyl which can have an oxygen atom as part of the chain, or aralkyl which can have an oxygen atom as part of the alkyl chain, their use for pharmacological and medicinal purposes, intermediates therefor and processes for their preparation.
摘要:
Beta-diketones substituted by an aryl-aliphatic group in which the aliphatic chain is interrupted by a cyclic group, and useful as anti-viral agents, are prepared by interacting the appropriate aryl-aliphatic halide with an alkali metal salt of a beta-diketone.

摘要:
SOLID ORGANIC POLYMERS NORMALLY SUSCEPTIBLE TO BURNING ARE RENDERED SELF-EXTINGUISHING BY INCORPORATING THEREIN A BROMINATED ARYLIDENE KETONE SUCH AS A BROMINATED BENZILIDENE OR CINNAMILIDENE KETONE; FOR EXAMPLE, 1,5-DIPHENYL-1,2,4,5-TETRABROMO-3 - PENTANONE. THE SELF-EXTINGUISHING AGENTS USEFUL IN THE INVENTION ARE UNEXPECTEDLY STABLE TO HYDROLYSIS, YET ARE HIGHLY REACTIVE AS SELF-EXTINGUISHING AGENTS.
摘要:
The present invention provides a convergent method for the synthesis of ubiquinones and ubiquinone analogues. Also provided are precursors of ubiquinones and their analogues that are useful in the methods of the invention.
摘要:
Compounds that provide non-teratogenic effects and lack irritation to the skin are shown in the formula below where the partially drawn ring signifies an aromatic ring which may be carbocyclic or heteroaromatic, 6-membered or 5-membered, and may be condensed with another ring. R.sub.1 is lower alkyl, Cl, Br, or I, R.sub.2 is H, lower alkyl, Cl, Br, or I, and R.sub.3 is lower alkyl, Cl, Br, I, or is an ether, thioether, ester, thioester, amine or substituted amine group. ##STR1##
摘要:
The present invention discloses pesticidally active compounds of formula (II) ##STR1## or a salt thereof, wherein Q is a monocylcic aromatic ring, or fused bicyclic ring system of which at least one ring is aromatic containing 9 or 10 atoms of which one may be nitrogen and the rest carbon each ring system being optionally substituted, or Q is a dihalovinyl group or a group R.sup.6 --C.tbd.C-- where R.sup.6 is C.sub.1-4 alkyl, tri C.sub.1-4 alkylsilyl, halogen or hydrogen; R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are the same or different with at least one being hydrogen and the others being independently selected from hydrogen, halo, C.sub.1-4 alkyl or C.sub.1-4 haloalkyl; and R.sup.1 is selected from hydrogen and C.sub.1-8 hydrocarbyl optionally substituted by dioxalanyl, halo, cyano, trifluoromethyl, trifluoromethylthio or C.sub.1-6 alkoxy and X.sup.1 is hydrogen, fluoro or chloro.

摘要:
2,2-Dimethyl-3-arylcyclopropanecarboxylic acids and esters, suitable as insecticide intermediates, of the formula ##STR1## in which Ar is naphthyl or substituted furyl, thienyl or phenyl, andR.sup.1 is hydrogen or alkyl, are produced by subjecting ##STR2## to radical polymerization to produce ##STR3## reacting that with chlorine or bromine to produce ##STR4## and reacting that with an alkali metal or alkaline earth metal hydroxide or carbonate. Various intermediates II and III are new.
