benzene(1) reacts with 3-butenoic, 4-pentenoic, 5-hexenoic and 2-methyl-4-pentenoic acids in CH2Cl2 to give tosyloxyacetones and with trans-3-hexenoic and 2-cyclopenteneacetic acids to give unsaturated lactones. 5-Norbornene-endo-2-carboxylic acid with 1 gives a rearranged lactone while 5-norbornene-endo-2,3-dicarboxylic acid gives a bis-lactone.
