The study of main-group molecules that behave and react similarly to transition-metal (TM)
complexes has attracted significant interest in recent decades. Most notably, the attractive …

The coexistence of a strong Lewis acid and a Lewis base in solution, the so called frustrated
Lewis pair, has led to the discovery of metal-free hydrogen activation. Since then, this …

Despite recent achievements in the field of frustrated Lewis pairs (FLPs) for small molecule
activations, the reversible activation and catalytic transformations of N–H-activated ammonia …

Given the growing demand for green and sustainable chemical processes, the catalytic
reductive alkylation of amines with main-group catalysts of low toxicity and molecular …

A catalytic, metal-free O–H bond insertion of α-diazoesters in water in the presence of B
(C6F5) 3· n H2O (2 mol%) was developed, affording a series of α-hydroxyesters in good to …

Described herein is the development of a borane-catalyzed cine-silylative ring-opening of α-
methyl azacycles. This transformation involves four-step cascade processes:(i) exo …

This work showcases a new catalytic cyclization reaction using a highly Lewis acidic borane
with concomitant C− H or C− C bond formation. The activation of alkyne‐containing …

The first frustrated Lewis pair‐catalyzed cycloisomerization of a series of 1, 5‐enynes was
developed. The reaction proceeds via the π‐activation of the alkyne and subsequent 5 …

Catalytic hydroarylation reactions of conjugated dienes are achieved using tris
(pentafluorophenyl) borane as a Lewis acid catalyst under mild reaction conditions. This …

The purpose of this review is to highlight ten years of success in the synthesis of six-
membered N-heterocycles using alkynes and nitrogen sources as substrates. It is our hope …
