Chalcogen-containing analogs of ethylene glycol and its derivatives
摘要:
Ethylene chlorohydrin when reacted with elemental chalcogens or dimethyl dichalcogenides in the hydrazine hydrate-alkali system forms chalcogen-containing analogs of ethylene glycol and its derivatives (dichalcogenated beta-diglycols, chalcogenated ethanols, and chalcogenated methyl cellosolves).
A facile access to chalcogen and dichalcogen bearing dialkylamines and diols
摘要:
A highly practical procedure for the preparation of novel classes of chalcogen bearing diamines [{H2N(CH2)n}E] and diols [{HO(CH2)n}(2)E] (n = 2 or 3 and E = Se or Te) by the reaction of disodiumchalcogenide and haloalkylamines or haloalcohols is presented.
