    • note
    • MS spectra and elemental analysis revealed 25 to consist as a 60:40 mixture of 25 and 26 that could not be separated either by distillation or chromatography. The formation of 26 results from a bromine - chlorine substitution during the formation of the acid chloride. To avoid this side reaction attempts were undertaken to synthesize the correponding 2-bromometacrylic bromide by the reaction of 24 with oxalyl dibromide. These reactions, however, did not result in the formation of significant amounts of the desired product but huge deterioration took place.

    • Under these conditions the product contains approx. 40% of 34 (cf. 16). In the following reactions only 28 gave the desired reactions very quickly but 34 was partially recovered.

    • Interestingly enough, neither a halogen exchange reaction occurs nor products resulting from a double addition reaction have been observed.
