Allenes are the simplest class of cumulenes, with two contiguous C C bonds, and show
unique physical and chemical properties. These features make allenes particularly attractive …

In the past four decades, allenes have progressively risen from an unenviable status of
being a structural curiosity to becoming one of the most powerful and versatile synthetic …

The development of new and highly efficient strategies for the rapid construction of intricate
molecular architectures is of great importance and remains a preeminent goal in current …

Allene–Verbindungen mit zwei benachbarten C C‐Bindungen–bilden die einfachste
Klasse unter den Cumulenen. Sie verfügen über außergewöhnliche physikalische und …

An emerging area of the nickel N-heterocyclic carbene (NHC) complexes and their
applications in homogeneous catalysis is highlighted in the review. The review paints a …

The three carbon atoms of allene moieties allow unique transformations and rapid
generation of complexity. Not surprisingly, allenes became extremely versatile building …

Conjugated dienes and polyenes are typically synthesized by sequential introduction of C═
C bonds. Here, we report a practical and scalable, catalytic dienylation that is highly regio …

A regio-and chemoselective sulfonylation of propargyl alcohols with sulfinamides in 1, 1, 1,
3, 3, 3-hexafluoroisopropanol (HFIP) was developed. It provided straightforward and mild …

An imino-Nazarov cyclization using α-aryl-substituted allenamides is described. This gold (I)-
catalyzed cascade is efficient and regioselective in constructing a diverse array of …

A strategy for synthesizing highly functionalized cyclohepta [b] indoles through a concise (4+
3) cycloaddition–cyclization–elimination sequence is described. The cycloaddition features …
