A Structurally Characterized Fluoroalkyne
Angewandte Chemie, 2017 AbstractThe facile synthesis of a stable and isolable compound with a fluoroalkynyl group, M−C≡CF, is reported. Reaction of [Ru(C≡CH)(η5‐C5Me5)(dppe)] with an electrophilic fluorinating agent (NFSI) results in the formation of the fluorovinylidene complex [Ru(=C=CHF)(η5‐C5Me5)(dppe)][N(SO2Ph)2].

Structure characterization of the 26S proteasome [PDF]
Biochimica et Biophysica Acta (BBA) - Gene Regulatory Mechanisms, 2011 In all eukaryotic cells, 26S proteasome plays an essential role in the process of ATP-dependent protein degradation. In this review, we focus on structure characterization of the 26S proteasome. Although the progress towards a high-resolution structure of the 26S proteasome has been slow, the recently solved structures of various proteasomal ...
