- Enzymatic resolution of (±)-2-endo-hydroxymethyl and acetoxymethyl substituted hexachloronorbornene derivatives
-
(±)-2-endo-Hydroxymethyl-1,4,5,6,7,7-hexachlorobicyclo[2.2.1] hept-5-ene and (±)-2-endo-acetoxymethyl-1,4,5,6,7,7-hexachlorobicyclo[2. 2.1]hept-5-ene were resolved by using various hydrolases to afford enantiomerically enriched products with ees of 94-98%. The absolute configuration was determined by transforming 2-endo-acetoxymethyl-1,4,5,6,7,7- hexachlorobicyclo[2.2.1]hept-5-ene into 2-endo-hydroxymethyl-bicyclo[2.2.1]hept- 5-ene with known absolute configuration.

- Synthesis of Some 5- and 5,6-Substituted 1,2,3,4,7,7-Hexachlorobicyclohept-2-enes and Their Insecticidal Activity
-
Forty five compounds of the title series have been synthesised from 1,2,3,4,5,5-hexachloro-1,3-cyclopentadiene and characterised by elemental analyses and IR and PMR spectral data.Their insecticidal behaviour against the 4th instar larvae of Aedes aegyptii (mosquito) is reported.Some of these compounds have also been tested against Musca domestica L (housefly).

- DIENOPHILIC ACTIVITY OF ALLYL HALOGENOACETATES IN REACTION WITH HEXACHLOROCYCLOPENTADIENE
-
The kinetics of the diene condensation of hexachlorocyclopentadiene with allyl monochloroacetate, monobromoacetate, and acetate were investigated by GLC.The kinetic and thermodynamic parameters of the reactions were determined.By a comparative analysis of the results it was shown that the nature of the electronwithdrawing substituent affects the dienophilic activity of the allyl esters in diene condensation with hexachlorocyclopentadiene.
