oxide (23g.) was passed at room temperature and the mixture was kept overnight in an ice-box. Solvent and reagent were removed in vacuo and the syrupy residue was used as such for the next process without purification.1,1-Bis(2-chloroethyl)-2,2-dimethylhydrazine Hydrochloride-Into suspension of 1,1-dimethy1-2, 2bis(2-hydroxyethyl)hydrazine (5g.) in CHCl3 (15cc.), SOCl2 (28g.) dissolved in CHCl3 (15cc.) was added dropwise under ice-cooling.After addition of SOCl2 was completed, temperature was gradually
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
