  • Short: II/24C
  • CAUTION! Many literature procedures employ NaH in DMF, and this system is often used routinely by research workers as a 'convenient' general purpose strong base. It should be noted, especially when considering scale-up of such reactions, that thermal runaways have been observed with NaH/ DMF, with self-heating beginning at temperatures as low as 26oC in some cases: Chem. Eng. News, 60(28), 5; 60(37), 5 (1982). A similar effect was also noted with N,N-dimethylacetamide. More recently also, incidents have been reported with other dipolar aprotic solvents 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone (DMPU) and Dimethyl sulfoxide (DMSO): Org. Process. Res. Dev., 7, 1030 (2003).
  • Short: II/24A

  • Widely used strong base for the irreversible formation of Na derivatives. If required, the protective oil can be removed by repeated washing and decantation with low-boiling petroleum, see, e.g.: Org. Synth. Coll., 6, 684 (1988), but for many purposes, this is not necessary, and the oil can be removed by incorporating a suitable extraction or washing step in the work-up. There are numerous Organic Syntheses references to reactions using NaH.
  • Used in the deprotonation of DMSO to form "dimsyl sodium", a useful strong base for e.g. the Wittig reaction: J. Org. Chem., 28, 1128 (1963).
