Abstract
An easily prepared series of phenylindenyldihydridosilyl ruthenium
complexes (2a–2d) was obtained by reaction of tertiary silanes with
the commercially-available [RuCl(3-phenylindenyl)(PPh3)2] (1). The
[RuH2(3-phenylindenyl)(SiEt3)] (2a) complex was shown to be highly
efficient (1.5mol%) in the ortho-selective borylation of pyridyl substrates,
with yields of up to 90%. A novel ruthenium(IV)-catalysed C–H activation
borylation/functionalization reaction using a remarkably low catalyst
loadings is described.
