(+/-)-2-Hydroxymethylbicyclo[2.2.1]hepta-2,5-diene. (+/-)-2-acetoxymethylbicyclo[2.2.1]hepta-2,5-diene and their hexachlorinated derivatives were resolved via CCL- and PLE-catalysed hydrolysis to afford enantiomerically enriched products with e.e.s of 61-93%. The absolute configurations were determined by transforming 2-hydroxymethylbicyclo[2.2.1]hepta-2,5-diene into the 2-formylbicyclo[2.2.1]hepta-2,5-diene with known absolute configuration.

[4 + 2]-Cycloaddition of hexachlorocyclopentadiene to para-substituted prop-2-yn-1-yl benzoates gave the corresponding 1,4,5,6,7,7-hexachlorobicyclo[2.2.1]hepta-2,5-dien-2-ylmethyl benzoates. The structure of the adducts was confirmed by independent synthesis, esterification of para-substituted benzoic acids with 1,4,5,6,7,7-hexachlorobicyclo[2.2.1]hepta-2,5-dien-2-ylmethanol.
