2,6-Bis(triisopropylsilyl)pyridine, an extreme example of the effect of strong steric screening on basicity
摘要:
2,6-Bis(triisopropylsilyl)pyridine (1) has been synthesized from 2,6-dibromopyridine. It is a very weak base in water since it does nor dissolve in 6N hydrochloric acid but does undergo protonation in nonaqueous media by triflic acid. (C) 1998 Elsevier Science Ltd. Ali rights reserved.
