TL;DR: In this article, the Arduengo carbenes 1,3-diisopropyl, 1,methyl-3-(1-methylpropyl)-, and 1-methyl 3-(2,4,6-trimethylbenzyl)imidazol-2-ylidene (3a-c) were reacted with MCl4(thf)2 (M=Zr, Hf) to yield the respective trans-(imidazeol- 2-ylidsene)MCl4 complexes 4a−c

The Catalyzed Nucleophilic Addition of Aldehydes to Electrophilic Double Bonds
TL;DR: A review of the literature of the catalyzed nucleophilic addition of aldehydes to electrophilic double bonds up to 1988 can be found in this paper, where the optimum conditions for thiazolium salt catalysis have been worked out.

Poly(1,1-bis(dialkylamino)propan-1,3-diyl)s; conformationally-controlled oligomers bearing electroactive groups
TL;DR: Evidence for a strong preference for all-anti conformations of the main chain in the naphthalenediamine oligomers is provided by ring current effects on 1H NMR shifts, and by X-ray structures, which also provide evidence of intercalation in the solid state.
