Influence of cyclodextrin complexation on photo-Fries rearrangement of sulphonyl derivatives
K Pitchumani P Velusamy M C Durai Manickam C Srinivasan
Cyclodextrin (CD) complexation shows remarkable selectivity in the photo-Fries rearrangement of sulphonate esters and sulphonanilide. An impressive regioselectivity is observed with meta-substituted sulphonate esters The results are explained on the basis of selective modes of complexation of the substrates within the CD cavity. The observed results are compared with those of the photo-Fries rearrangement of esters and anilides.

Syntheses of organic benzyl sulphides from thiols using a modified clay catalyst
P Kannan H Shayira Banu K Pitchumani
The reaction between benzyl chlorides and thiols is catalysed efficiently by a new basic clay, Cat-1 prepared by introducing 3-aminopropyltriethoxysilane into clay interlayers of K-10 and KSF montmorillonites, as well as bentonite clays affording high yields of the corresponding sulphides.
