Synthesis and Reactivity of Boron Triflate and Bistriflimide Complexes Bearing Two ortho-Carboranes

Abstract. This work discloses the synthesis of boron complexes featuring two 1-methyl-ortho-carborane substituents (MeoCb) and a weakly coordinating pseudo

Transient bis(carboranyl)boryl anions

The reduction of bromoboranes with two ortho-carborane substituents results in the generation of transient boryl anions. DFT computations reveal that their

Silicon–carbon bond cleavage from a hydroboration sequence

The reactions of internal pyridyl/trialkylsilyl alkynes with the potent hydroboration reagent bis(1-methyl-ortho-carboranyl)borane (HBMeoCb2) results in un

1,4-Bromoboration of nitroalkenes

The selective 1,4-bromoboration of nitroalkenes occurs under mild conditions with a bromoborane featuring two 1-methyl-ortho-carborane substituents, BrBMeo

Reactivity of gold and copper acetylide with a secondary borane

Gold(i) triphenylphosphine phenylacetylide reacts with bis(1-methyl-ortho-carboranyl)borane to give a hydroboration product that is best described as an η2

Frustrated Lewis Pair Reactivity of Bis(1-methyl-ortho-carboranyl)borane

Abstract. Carboranyl substituted boranes are attractive Lewis acids for frustrated Lewis pair (FLP) chemistry due to their tremendous bulk and high Lewis a

Flash Communication: Reactions of Borole with Michler’s Ketone Versus Thioketone

Abstract. In this work, we interrogate the reactivity of pentaphenylborole with 4,4′-bis­(dimethylamino)­benzophenone (Michler’s ketone) and its heavier co

A tribute to the life and legacy of Prof. Stephen A. Westcott

Reactions of Borafluorene with Iminophosphines: PN Insertion and Skeletal Editing to Phosphafluorene

Abstract. The reactions of iminophosphines (Mes*N=PR, Mes* = 2,4,6-tri-tert-butylphenyl) with 9-phenyl-9-borafluorene resulted in the isolation of two dist

A Crystalline Boravinylidene from an Arrested Hydroboration Reaction

Abstract. Boravinylidenes are intermediates in 1,1-hydroboration reactions of alkynes en route to vinyl boranes. Unlike transition metal-vinylidene complex

Müller versus Gutmann–Beckett for assessing the Lewis acidity of boranes†

A 19F NMR spectroscopic probe, p-fluorobenzonitrile, is used to evaluate the relative Lewis acidity of boranes. The resulting scale is compared with the Gu

Cyclopentadienyl cations

This perspective covers the chemistry of cyclopentadienyl cations from the first synthetic attempts generating transient variants to their successful isola
