Materials and Instruments 
Chemicals were purchased from the Merck chemical companies. Thin-Layer Chromatography 
(TLC) on commercial plates of silica gel 60 F254 was used to monitor the progress of reactions. 
The products were characterized by FT-IR spectra, 1HNMR, 13C NMR. FT-IR spectra were 
recorded on Shimadzo FT-IR 8400 instrument. 1H and 13CNMR spectra were recorded on 
Bruker Advance Spectrometer 300 MHz and 75 MHz respectively, using CDCl3-d as solvent. 
The chemical shifts are expressed in parts per million (ppm) and tetramethylsilane (TMS) was 
used as an internal reference. Melting points were recorded on a THERMO SCIENTIFIC 9100 
apparatus. 
General procedure for the synthesis of α,α′-bis(substituted-
benzylidene)cycloalkanones (3) 
A mixture of cyclohexanone (1 mmol), aromatic aldehyde (2 mmol) and 0.032 g n-TSA was 
stirred at 90 °C under solvent-free condition for an appropriate time. After completion of the 
reaction (monitored by TLC), hot ethanol was added and the catalyst was filtered. The title 
compounds were obtained in their yellowish crystalline forms by recrystallization of ethanol 
solution. 
General procedure for the synthesis of xanthenes (5) 
A mixture of α,α′-Bis(substituted-benzylidene)cycloalkanones (1 mmol), dimedone (1 mmol) 
and 0.012 g n-TSA was added in a test tube and heated in an oil bath  at 130 °C under solvent-
free condition for an appropriate time. After completion of the reaction (monitored by TLC), 
hot ethanol was added and the catalyst was filtered. The products were obtained in white 
powder by recrystallization of ethanol solution.
