In Room temperature phosphorescence of α-bromonaphthalene induced by cyclodextrin in the presence of hexahydropyridine or 1-ethylpiperidine and its application is described. The highest yields of 5-Bromopyrimidine (37%) were obtained by using 1-ethylpiperidine or triethylamine as condensing agent. Tributyltin hydride and 1-ethylpiperidine hypophosphite were mediated intermolecular radical additions to 2, 4, 6-trichlorophenyl vinyl sulfonate.

Hindered, non-nucleophilic base. Preferred base for enantioselective crossed aldol condensations of Sn enolates: Tetrahedron, 40, 1381 (1984). Also found to give excellent results in the formation of anhydrides using Bis(2-oxo-3-oxazolidinyl)phosphinic chloride, L08775: Synthesis, 616 (1981). Has been used in peptide synthesis via pivaloyl mixed anhydrides: Coll. Czech. Chem. Commun., 27, 1273 (1962).
