Treatment of N-1-(2, 2-dichloroalkylidene)t.butylamines 1a-c with excess methanolic sodium methoxide under reflux afforded mainly a mixture of α-methoxy-α,β-unsaturated aldimines 2a-c and the rearrangement products 3, besides small amounts of N-t.

1,2,2-Trisubstituted aziridines have been prepared by reduction of secondary N-1-(2-chloroalkylidene)amines with lithium aluminium hydride. N-Substituted 1-azaspiro[2.5]octanes (spiroaziridines) have been synthesized by this method. Under appropriate

Chloride ions formed during the chlorination of ketones with sulfuryl chloride catalyze the production of chlorine. The phenomenon can be suppressed by addition of chlorosulfonic acid, causing a significant change in the regioselectivity of chlorinat

Reaction of the monomethyl enol ethers of 3-chloro-2,4-pentanedione and 2-chloro-1-phenyl-1,3-butanedione with sodium methoxide in methanol gave hydroxy enol ethers, respectively 3-hydroxy-2,4,4-trimethoxy-1-pentene and 3-hydroxy-2,4,4-trimethoxy-4-p

Tetrahydrofuran was chlorinated in the presence of N,N-dimethyloctylamine (1 mmol per mol optimal) with an excess of sulfuryl chloride at 55-80°C. After a first stage producing trans 2,3-trichloro THF (1) the reaction proceeded to complete conversio

Experimental evidence is provided that the rearrangement of N-aryl α,α-dichloroketimines with lithium aluminium hydride in ether, observed as a competitive reaction during the stereospecific synthesis of cis-aziridines, proceeds via consecutive tra

1-Aryl-2,2-dichloro-1-alkanones were shown to rearrange with methyl magnesium iodide in ether under reflux into highly sterically hindered alkohols. The mechanism proceeds by a pseudo pinacol type rearrangement of the initially formed carbonyl adduct
