The analogous preparation of NaH and KH was found to require the prior in situ generation of highly active BuNa and BuK, respectively, by reaction of sodium or potassium tert-butoxide with n-butyUithium the commercial hydrides are less active and insoluble in hexane. The utility of the superactive forms of these hydrides in reductions and metallations has been described .
