Abstract
The relative rates of protodeboronation of
benzene-, thiophen-2-, and thiophen-3-boronic acids at 70� determined by an
extrapolation procedure, are 1 : 7.1 x 103 : 8.5 x 105.
The relative reactivity for 2-substitution thus exceeds that found for any other
electrophilic substitution of thiophen.
