Esters of o-and m-carborane-C-carboxylic acids with o-and m-C-carborane alcohols

Acid chlorides of o-and m-carborane-C-carboxylic acids reacted with primary o-and m-C-carborane alcohols in anhydrous benzene to form previously unknown corresponding o-and m-carborane-containing two-and three-nuclear esters.

Esters of isoxazole- and isothiazolecarboxylic acids and oximes of β-isatin, isoxazole- and ferrocene-containing ketones and carborane alcohols

Oximes of β-isatin, isoxazole- and ferrocene-containing ketones, o- and m-carborane alcohols react with isoxazol- and isothiazolecarboxylic acid chlorides in the presence of triethylamine to afford the corresponding esters.

Synthesis of o-carborane-C-carboxylates of certain natural terpene alcohols, sterols, phenols, and camphar oxime

Previously unreported esters 1b–20b were synthesized from natural terpene alcohols, sterols, plant phenols, and camphar oxime (1a–20a) by reaction with o-carborane-C-carboxylic acid chloride.

Synthesis of esters of metallocene alcohols and 4,5-dichloroisothiazol-3-carboxylic and 5-arylisoxazole-3-carboxylic acids

Acylation of alkyl- and 1,1′-dialkylferrocene alcohols and diols as well as (3,4,4-trichlorobut-3-ene-1-ol-1-yl)-4,5-cymantrene with dichloroisothiazole- and 5-arylisoxazole-3-carbonyl chlorides has afforded esters containing 1,2-azoles fragments. Some of the obtained compounds have exhibited potentiating action in the binary mixtures with insecticides.

Synthesis of iodinated meta-carboranecarboxylic acids

A new method for introduction of one and two iodine atoms into the meta-carborane fragments containing carboxy groups at the core carbon atoms C1/C2 was developed. Reaction proceeded in acetic acid at heating in the presence of concentrated nitric and sulfuric acids.

Synthesis of azomethines based on 4-formylphenyl m-carboranyl-C-methanoate

A preparative method for the synthesis of m-carborane azomethines via the condensation of mcarborane-C-4-formylphenyl methanoate with aliphatic, cycloaliphatic, and aromatic amines was developed.

Synthesis of Functionally Substituted Diacetylenic Alcohols and Carboxylic Acids

Diacetylenic alcohols were synthesized by the Glazer reaction of 1-alkynes with 1-alkyn-ω-ols. p- and m-Alkadiyne bezoic acid derivatives were prepared by the Cadiot-Hodkiewicz reaction of p- and m-ethynylbenzoic acid with 1-bromoalkynes.

Synthesis of 2-alkoxy-4-[N-(alkyl, cycloalkyl, aryl)imino]phenyl m-carboranecarboxylates

Previously unknown m-carborane-containing azomethines (Schiff bases) were synthesized by the reaction of esters derived from vanillin or vanillal and m-carboranecarboxylic acid with primary amines in absolute methanol.

Functional Derivatives of Ethyl 4-(Chloromethyl)-2,6-dimethylpyridine-3-carboxylate

The condensation of ethyl 4-(chloromethyl)-2,6-dimethylpyridine-3-carboxylate with substituted phenols in ethanol in the presence of potassium carbonate afforded the corresponding aryl pyridin-4-ylmethyl ethers. Analogous condensation with substituted anilines gave 2-aryl-4,6-dimethyl-1,2-dihydropyrrolo[3,4-c]- pyridin-3-ones. Esters containing 1,2-azole fragments were synthesized by acylation of hydroxymethylsubstituted ethers with 5-arylisoxazole- and 4,5-dichloroisothiazole-3-carbonyl chlorides.

Synthesis of N’-substituted derivatives of 5-(4-methylphenyl)isoxazole-3-carbohydrazonamide

Condensation of aromatic, isoxazole, and ferrocene aldehydes as well as 1,1’-diacetylferrocene with 5-(4-methylphenyl)isoxazole-3-carbohydrazonamide afforded various N-substituted azines with molecular fragments of the corresponding aldehydes or diacetylferrocene.
