Poly(ethylene glycol) (PEG) has been used as a medium for deprotection of 1,1-diacetates with easy recyclability of solvent and indium tribromide catalyst for the first time. Several aryl 1,1-diacetates were deprotected to the corresponding parent aldehydes in high yield. The procedure is operationally simple and environmentally benign.
