Abstract
![]()
Herein, we describe
a study of the synthesis, characterization,
and catalytic properties of a cis-dichlorido seleno-chelated
Hoveyda–Grubbs type complex (Ru8). Such a complex
has been obtained through a straightforward and high-yielding synthetic
protocol in three steps from the commercially available 2-bromobenzaldehyde
in good overall yield (54%). The catalytic profile, especially the
latency of this complex, has been probed through selected olefin metathesis
reactions such as ring-closing metathesis (RCM), self-cross-metathesis
(self-CM) and ring-opening metathesis polymerization (ROMP). In addition
to its high latency, the selenium Hoveyda-type complex Ru8 exhibits a switchable behavior upon thermal activation. Of interest,
while the corresponding sulfur-chelated Hoveyda type catalyst is reported
to be only activated by heat, the selenium analogue was found to be
active upon both heat and light irradiation.
