Versuchsvorschrift
A mixture of 5.83 g (22.2 mmol) of triphenylphosphine and 5.00 g (23.0 mmol) methyl 4-nitrobenzenesulfonate was allowed to react for 2 hrs at 145° C. A total of 10.3 g (21.5 mmol, 96.8%) of the product was obtained, which was further purified by recrystallization from 90:10 toluene-acetonitrile. Analyses: mp 127.0°-128.6° C.
