Investigation of the recently reported ortho-carboranyl iodine(III) compound, 1I(OTf)2 (1I = 1-iodo-2-methyl-8,9,10,12-tetrachloro-o-carborane), a species previously only observed in solution, has resulted in an improved synthesis via Si(OTf)4 and 1IF2 ...

A new family of electron-poor Au(III) cations bearing bistriflimide or triflate ligands is reported. These cations can undergo direct C─H metalation with simple arenes to give mono-aryl cations. Subs....

Structural confirmation of an iodine(V) analogue of Weiss’s reagent, [ArI-O(Pyr)2]2+, is reported using monodentate pyridine ligands and a nitro-substituted arene to provide protection from electrophi...

The first C-bound ortho-carborane (oCb) supported hypervalent iodine(III) -IL2 type species are reported in RoCb-IL2, for L = F and OTf, including two structurally verified -IF2 examples. Initial synthetic observations and supporting theoretical calculations suggest that the new oCb-IL2 type compounds will be more reactive than any known Ar-IL2 compound. This is exemplified by a previously unobserved oxidative demethylation of trimethylsilyl fluoride, suggesting that many substrates unreactive toward Ar-IL2 could be susceptible to oxidation by oCb-IL2.

Boravinylidenes are intermediates in 1,1-hydroboration reactions of alkynes en route to vinyl boranes. Unlike transition metal-vinylidene complexes, boravinylidenes have hitherto, not been crystallogr...
