The Bi(III) catalysed O-acylative cleavage of cis- and trans-2,5- dimethyltetrahydrofuran 4 with AcCl, BzCl or i-PrCOCl is stereochemically consistent with the operation of a concerted process (AND N), which proceeds via a stabilised carbocation or '...

The mild (DCM/20°C), quantitative, regioselective, O-acylative cleavage of tetrahydrofurans using organic acid halides with catalytic Bi(III) halides is reported. X-ray crystallography is used to rationalise the failure of the reaction in the case of...
