Monsigny, Louis; Cejas Sanchez, Joel; Piatkowski, Jakub; Kajetanowicz, Anna; Grela, Karol published their research in Organometallics in 2021. The article was titled 《Synthesis and Catalytic Properties of a Very Latent Selenium-Chelated Ruthenium Benzylidene Olefin Metathesis Catalyst》.Safety of Ethyltriphenylphosphonium bromide The article contains the following contents:
Herein, authors 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 com. 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 analog was active upon both heat and light irradiation The results came from multiple reactions, including the reaction of Ethyltriphenylphosphonium bromide(cas: 1530-32-1Safety of Ethyltriphenylphosphonium bromide)
Ethyltriphenylphosphonium bromide(cas: 1530-32-1) is a phase transfer catalyst, used to accelerate the cure of phenolic-based epoxy resins, certain fluoroelastomer resins and thermosetting powder coatings. It is also used as catalysts in the synthesis of certain organic compounds and as a pharmaceutical intermediate.Safety of Ethyltriphenylphosphonium bromide
