Results and discussion 
Reaction products of chlorinesulfamidation of unsaturated compounds with chloramines have 
an important role for synthesizing N-substituted derivatives of sulfamides which are syntons for the 
synthesis of multifunctional and heterocyclic derivatives. Recently this reaction has been used for 
aminohydroxylation, aminochalcogenation, epoxydation, aziridination, allyl amination of alkenes, 
during hetarylation and so on. It is supposed that [1], the reactions with chloramines proceed with 
constants of rate 10

constants of rate 2·10

The reaction of unsaturated compounds with N,N-dichloramides of sulfo acids occurs fre-
quently under the effect of UV-radiation or using catalysts. Study of interaction reaction of N,N-p-
chlorbenzenesulfamide with allylchloride in ССl
4
both under the effect of UV-radiation or using 
dicyclohexylperoxidecarbonate and in their absence showed advantage of the first method [2]. 
However, together with the main products other compounds are also formed during rearrangements, 
that confirms ion-radical reaction. Maybe that’s why telomerization of acrylonitrile occurs during 
the reaction with acrylonitrile. It was shown that [3] catalytic reaction of N,N-dichlor-p-
toluenesulfamide with β-nitrilestyrene leads to aminohalogenation with high yield. Unlike them the 
reaction of N,N-dichlor-p-toluenesulfamide with alkenes in the presence of palladium results in not 
only adducts, but also aziridination [4]. Stereoselective addition of monochloramides of sulfo acids 
to unsaturated compounds proceeds with promoter СО

[5] or copper (1+) catalyst [6].
Stereoselective addition occurs during the reaction of monochloramines with derivatives of al-
lyl alcohol and cis- and trans-isomers of hydroxyazipyridines are formed [7].
N-substituted sulfamides were produced during interaction of N,N-dichlor-4-chlorbenzene- or 
N,N-dichlor-4-methylbenzenesulfamides with phenylacetylene [8].
Our studies [9-11] showed that the most convenient reagents for chloramidation of unsaturat-
ed compounds are N-monochloramides of benzenesulfo acids (chloramine -B, -T, KhB and so on).
A new method of chlorination of olefins has been developed [12]. Under the effect of elec-
tron-acceptor sulfamide fragment, halides in N-2,3 position is easily substituted with nucleophiles. 
Sulfamides containing N-2,2-dichlorethyl groups with phenyldiamine form quinoxaline [13], halo-
gen in sulphonylaziridine
 
even in β-position is easily substituted resulting in benzothiazepine [14]. 
The effect of complex ether group on chloramidation reaction of acrylic ether with monochlo-
ramine – B was studied and reactivity of chlorine atom in the compounds was investigated. It was 
found that the reaction of chloramine-B with butyl ether of acrylic acid, aminly, depends on solvent 
and temperature of the reaction. During the reaction chloramidation occurs in aprotic solvent (ben-
zene, toluene):

The formation of the compound (XV) proves that synthesized compounds may be synthons 
for heterocyclic compounds 
Preliminary researches of synthesized compounds showed their high antimicrobial properties. 
Thus, using monochloramine as a key reagent it is possible to synthesize multifunctional sul-
famide compounds which are 1,3- dipolarophils. Therefore they, in turn, are synthons for synthesis 
of various heterocyclic compounds. Furthermore, by the reaction of chloramine with butyl acrylate, 
it is possible to easily synthesize compounds with various functional groups that are difficult or im-
possible to obtain in another way.
