Tautomerization of 2,6-lutidines in the presence of B(C6F5)3 using catecholborane as a precatalyst†
Abstract
2,6-Lutidine and its derivatives in the presence of B(C6F5)3 undergo tautomerization to yield the corresponding enamine·B(C6F5)3 adducts when catecholborane is applied as a precatalyst. This reaction provides a straightforward way for benzylic C–H borylation of lutidines.
