  • • Reacts with 1,2-diols to form 5-membered cyclic dibutylstannoxane derivatives. For use in the glycoside field, see: Synthesis, 409 (1995). Formation of these derivatives is greatly accelerated by microwave irradiation: Synlett, 89 (1994). The stannylene derivatives are activated to electrophilic attack:
  • • With bromine, the ɑ-hydroxy ketone is formed: J. Chem. Soc., Perkin 1, 1568 (1979). With acyl or sulfonyl chlorides, overall regioselective monoacylation of the diol at the more substituted hydroxyl can be achieved: Tetrahedron Lett., 21, 221 (1980); J. Chem. Soc., Chem. Commun., 1457 (1985); J. Org. Chem., 55, 5132 (1990); 61, 5257 (1996). Selective monotosylation of 1,2-diols has also been achieved catalytically: Tetrahedron Lett., 41, 3773 (2000).
  • • Catalyst for lactonization and lactamization reactions: J. Am. Chem. Soc., 102, 7578 (1980), particularly useful in the formation of macrolides: J. Am. Chem. Soc., 105, 7130 (1983). For catalysis of N-acylation of hydroxy alcohols with microwave irradiation, see: J. Org. Chem., 61, 5264 (1996).
  • • Promotes the cycloaddition of Trimethylsilyl azide, L00173 to nitriles to give 5-aryltetrazoles, some of which are important as angiotensin II inhibitors: J. Org. Chem., 58, 4139 (1993):
  • • Catalyst for the dehydration of amides to nitriles under neutral conditions: Synthesis, 1724 (1999); for use of microwave irradiation, see: J. Org. Chem., 64, 1713 (1999).
