Miscellaneous 5- substituted

Structure and Stereochemistry (it is self-subdivided into Theoretical Aspects, Stereochemical Aspects, Betaines and Other Unusual Structures, Miscellaneous Substituted Heterocycles). [Pg.148]

Miscellaneous Substitution Reactions.—A reaction cycle has been described for the synthesis of non-geminal bromofluorocyclotriphosphazenes NaPaFa Br ... [Pg.269]

This section deals with the generation and reactivity of carbanions, carbenium ions and carbon radicals adjacent to the thiophene ring. A few miscellaneous substituted alkyl groups will also be covered. [Pg.562]

Cyclic systems Miscellaneous substituted Ca-acid derivatives... [Pg.69]

Miscellaneous substituted Cs-acid derivatives 3.1.7.1 p-Heteroatom substituted derivatives... [Pg.129]

Miscellaneous Substitution Reactions (mostly Nucleophilic).— The 5-halogen-substituent in isothiazoles is readily replaced by nucleophilic substitution with alkoxy- or hydroxy-groups this provides a route to 5-alkoxy-3-methyl-4-nitroisothiazoles and 5-hydroxy-4-nitroisothiazoles. 4,5-Dihromo-3-methylisothiazole affords the 5-butoxy-compound on treatment with sodium butoxide in butanol, and the 5-hydroxy-compound with methanolic sodium hydroxide, but fails to react with sodium methoxide. ... [Pg.570]

Miscellaneous Substitutions.— The enhanced reactivity of the 2-methyl group in thiazole is illustrated by the hydroxyalkylation of 2,4-dimcthyl-thiazole to the alcohols (62), on successive treatment with lithium amide in liquid ammonia, and with a carbonyl compound the products are readily dehydrated to the ethylenes (63). ... [Pg.599]

Other miscellaneous substitutions include the attempted bromination, acetoxymercuration, tritylation, idoination, lithiation, Vilsmeier, and diazocoupling reactions on the l,6-dioxa-6aA -thiapentalene system (88) electrophilic reaction occurs at positions 3 (and 4). The few attempts at electrophilic substitution in arsabenzene have been reviewed. ... [Pg.286]
