A new [4+2] cycloaddition of allenyne-alkyne is developed. The reaction is believed to proceed with forming an α,3-dehydrotoluene intermediate. This species behaves as a σπ-diradical to react with a hydrogen atom donor, whereas it displays a zwitt

Metallaaromatics constitute a unique class of aromatic compounds where one or more transition metal elements are incorporated into the aromatic system, the parent of which is metallabenzene. One of the main concerns about metallabenzenes generally de

The hexadehydro Diels–Alder (HDDA) reaction has recently emerged as a powerful tool for aryne formation, thereby giving access to highly functionalized aromatic skeletons. In this chapter, we describe an HDDA-based approach to the total synthesis o

A facile formal ene reaction of trisubstituted silylallenes with triplet molecular oxygen involving the cleavage of a H–C(sp2) bond has been described. For this formal ene reaction, the silyl substituent was found to be critical to induce peroxide

Ruthenium alkylidene complexes are prepared via enyne ring-closing metathesis relying on the exo and endo gem-dialkyl substituent effect. The structural features stabilizing oxygen-chelates are explored and confirmed by single crystal X-ray diffracti
