Since Ferns and Lapwarth2have pointed out the fact that the group R-SOB-O- functions as a halide atom, i t is evident that the replacement of a tosyl group on an asymmetric carbon atom may be accompanied by a Walden inversion. Indeed in the sugar series such occurrences were reported first by Mathers and Robertson3 and later by Oldham
