Synthesis and Characterisation of Degradable Thermosetting Materials [PDF]
, 2012 Traditional thermosetting materials generally display good durability, yet poor tractability, reworkability, and degradability. This project, however, provides a class of thermoset ring-opening metathesis polymerization (ROMP) materials based on ...

Backbone tuning in indenylidene-ruthenium complexes bearing an unsaturated N-heterocyclic carbene
, 2010 The steric and electronic influence of backbone substitution in IMes-based (IMes = 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene) N-heterocyclic carbenes (NHC) was probed by synthesizing the [RhCl(CO)(2)(NHC)] series of complexes to quantify ...

Dual Activation of H2 and CO2 by a Pincer‐Type Ni–Zn Heterobimetallic Complex
Angewandte Chemie, EarlyView.A bimetallic Ni−Zn complex performs sequential activations of H2 (1 equiv) and CO2 (2 equiv). This bimetallic cooperativity is attributed to the weak Lewis acidic nature of Zn(II), which promotes fluxional ligand binding. Namely, an X‐type ligand at Ni, where X is hydride or formate, toggles between two different binding modes: bridging Zn(μ‐X)Ni and ...

First Total Synthesis of Cryptopyranmoscatone A3 and Cryptopyranmoscatone B4
SynOpen, 2018 The first total synthesis of cryptopyranmoscatones A3 and B4 has been accomplished from d-ribose or but-3-ynol. The key steps involved in the synthesis are oxa-Michael addition, highly diastereoselective Brown allylation, and ring closing metathesis ...

Light-induced olefin metathesis
Beilstein Journal of Organic Chemistry, 2010 Light activation is a most desirable property for catalysis control. Among the many catalytic processes that may be activated by light, olefin metathesis stands out as both academically motivating and practically useful.

Metathesis Cascade-Triggered Depolymerization of Enyne Self-Immolative Polymers
, 2021 A novel class of enyne self-immolative polymers (SIPs) capable of me-tathesis cascade-triggered depolymerization is reported. Studies on mod-el compounds established 1,6-enyne structures for efficient metathesis cascade reactions.

Selenopeptide Transamidation and Metathesis
Organic Letters, 2014 Selenopeptides can be transamidated by cysteinyl peptides in water using mild conditions (pH 5.5, 37 °C) in the presence of an arylthiol catalyst. Similar conditions also catalyze the metathesis of selenopeptides. The usefulness of the selenophosphine derived from TCEP (TCEP═Se) for inhibiting the TCEP-induced deselenization of selenocysteine residue ...
