Reaction of alpha,omega-bis[tris(trimethylsilyl)silyl]alkanes with one equi
valent of potassium tert-butoxide resulted in clean formation of mono-potas
sium silyl anions. Addition of another equivalent of the transmetallating a
gent led to the formation of the di-potassium compounds. Partial hydrolysis
of the dipotassium compounds induced an intramolecular reaction yielding a
cyclic silyl potassium compound. (C) 1999 Published by Elsevier Science Lt
