A halide abstraction reagent applied in the etherification of alcohols with primary alkyl halides,1 and generation of cationic rhodium catalysts from chlororhodium complexes for the hydrophosphination of acetylenes.2 Also employed as a catalyst for the preparation of silyl ethers by hydrosilylation of aldehydes,3 synthesis of 1-(isoquinolin-1-yl)guanidines via a three-component reaction of 2-alkynylbenzaldehyde, sulfonohydrazide, with carbodiimide,4 cyclization of enynals or enynones with amines,5 cyclopropenation of internal alkynes using donor-/acceptor-substituted diazo compounds as carbenoid precursors,5 reaction of 2-Alkynylbenzaldoxime with amine to afford 1-aminoisoquinolines,6 cycloisomerization of a variety of allenynamides,7 and the cross-dehydrogenative-coupling of terminal aromatic alkynes and benzylic ethers.8
