TL;DR: A series of nickel complexes with β-ketoiminato ligands based on pyrazolone derivative were synthesized and characterized, which are highly active catalyst precursors for norbornene polymerization under mild reaction conditions through a vinyl-type polymerization mechanism as discussed by the authors.

TL;DR: Thymine functionalised poly(norbornene)s are synthesised via living ring-opening metathesis polymerisation using the ruthenium initiator.

TL;DR: The aziridine toluene-p-sulfonamide as discussed by the authors was shown to give β-silylethyl sulfonamides, which is an anomalous result.
Abstract: The toluene-p-sulfonamides of secondary amines and indoles are cleaved by treatment with phenyldimethylsilyllithium to give the secondary amines. Aziridine toluene-p-sulfonamides, however, are opened by attack of the silyllithium reagent on carbon to give β-silylethyl sulfonamides. The aziridine toluene-p-sulfonamide 22 derived from norbornene is different in giving the 2-[dimethyl(phenyl)silyl]-4-methylbenzenesulfonamide 23 of exo-norbornylamine. The aziridine toluene-p-sulfonamides 26, 28 and 30, derived from methyl cinnamate, methyl acrylate and cinnamyl acetate, are also anomalous, giving 3-[N-(p-tolylsulfonyl)amino]-3-phenylpropionic acid 27, {3-[N-(p-tolylsulfonyl)amino]propionyl}dimethyl(phenyl)silane 29 and trans-cinnamyl alcohol 31, respectively, each derived by opening of the aziridine ring followed by loss of the silyl group.

TL;DR: The 3rd generation Grubbs initator (H 2 IMes)(3-bromopyridine) 2 (Cl) 2 Ru=CHPh (1) accomplishes the synthesis of ABC triblock copolymers via living ring-opening metathesis polymerisation (ROMP) of norbornene derivatives as mentioned in this paper.
Abstract: The 3 rd generation Grubbs initator (H 2 IMes)(3-bromopyridine) 2 (Cl) 2 Ru=CHPh (1) accomplishes the synthesis of ABC triblock copolymers via living ring-opening metathesis polymerisation (ROMP) of norbornene derivatives. Complete initiation and an outsanding tolerance of functional groups are provided, which is proven by a combined study by means of matrix-assisted laser desorption/ionisation mass spectrometry, gel permeation chromatography and NMR spectroscopy on an ABC triblock cooligomer.

TL;DR: In this article, a ring-opening metathesis polymerization of norbornene was performed in the presence of vanadium(V)-alkylidene and ordinary Mo(CHCMe2Ph)(N-2,6-iPr2-C6H3)(OtBu)2.
