Abstract

In a typical experiment (run 7), N-methyl-3-hydroxy piperidine (20 mmol) in 10 ml of dry THF was added dropwise to a suspension of NaH (60 mmol), Ni(OAc) 2 (10 mmol) in dry THF (30 ml) at 65°C. After 2 h of stirring, the reagent was ready for use and 4-methyldibenzothiophene (2 mmol) could be added in dry THF (10 ml). The reaction was monitored by GC analysis of small aliquots using internal standard method. After completion of the reaction, the excess of ...
