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

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
2
[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):

Synthesized derivatives of butyl ether of acrylic acid are dipolar compounds, that’s why there
is 1,3-dipolar addition to
polarophiles.
Multifunctional compounds II –

synthesis of heterocyclic compounds.
Despite sterically hindered structure the compound II with acetylacetone forms N-

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.
