green and sustainable chemistry. Ferrocene is one of the important homogeneous catalysts
for the oxidation and hydroxylation of aromatic compounds due to its redox centre, π-
conjugation system and exclusive electron transfer ability [1]. Recently, ferrocene has been
heterogenized on SBA-15 support via multi-step post-synthetic grafting method [2]. A
versatile synthetic methodology has recently been reported for the condensation of primary …
