Palladium/carbon catalytic aromatic functional group on the adjacent position iodizate method
-
Paragraph 0027-0029, (2017/06/14)
The invention discloses a method for iodization of an ortho-position of a functional group on a palladium/carbon catalytic aromatic ring. The method comprises the following steps: mixing an aromatic ring of which a substrate contains a functional group, a

, p. 3800 - 3806 (2012/07/17)
Novel insecticidal anthranilamides with elaborated sulfur-containing groups are described. The synthesis of compounds with functional groups such as sulfoximines and scarcely reported groups such as sulfonimidoyl hydrazides and hydroxylamides, their in vitro and in vivo biological activity as well as their physical properties are reported.
PROCESS FOR PRODUCING 2-HALOGENOBENZAMIDE COMPOUND
-
Page/Page column 13-15, (2008/06/13)
A novel process for producing a 2-halogenobenzamide compound useful as a raw material or active ingredient for medicines and agricultural chemicals. The process, which is for producing a 2-halogenobenzamide compound represented by the general formula (I): (wherein R1, R2, R3, R4, and R6 may be the same or different and each represents hydrogen or C1-6 alkyl; R5 represents C1-6 alkyl; k is 1 or 2; Y1, Y2, Y3, and Y4 may be the same or different and each represents hydrogen, halogeno, etc.; and X represents chlorine, bromine, or iodine), is characterized by reacting an benzamide compound with a halogenating agent in the presence of a palladium catalyst to obtain a substituted benzamide compound and then reacting the resultant substituted benzamide compound with an oxidizing agent after or without isolating the substituted benzamide compound.

, (2008/06/13)
The present invention provides a process for producing 2-halobenzoic acids of the general formula (I), characterized by reacting a benzoic acid of formula (II) with a halogenating agent in the presence of Pd catalyst: (wherein A is —OH, —OM (M is alkali metal), —N(R6)R7 (R6 and R7 are each H, C1-C6 alkyl, optionally substituted phenyl, or the like) ; R is H, C1-C6 alkyl, C1-C6 alkylcarbonyl, carboxyl, C1-C12 alkoxycarbonyl, optionally substituted phenylcarbonyl, or the like; n is 0 to 4; X is Cl, Br or I, or alternatively (R)n may be present on benzene-constituting carbon atoms adjacent to each other and form a C3-C4 alkylene- or C3-C4 alkenylene-fused ring).
