12-Chloro-6-cyclo­hexyl-5,6,7,12-tetra­hydro­dibenzo[c,f][1,5]aza­stibocine

In the title organometallic complex, [Sb(C20H23N)Cl], the central anti­mony-containing part of the complex exhibits a pseudo-trigonal-bipyramidal geometry, where two C atoms and a lone electron pair of the Sb atom exist at the equatorial positions, while the N and Cl atoms are located at the apical positions, and a transannular inter­action exists between the Sb and N atoms on 1,5-aza­stibocine. Inter­molecular C—H⋯Cl hydrogen bonds are also observed

Palladium- and base-free synthesis of conjugated ynones by cross-coupling reactions of alkynylboronates with acid chlorides mediated by CuCl

Alkynylboronates can be employed as a practical and versatile precursor for a variety of pi-conjugated organic compounds. In the presence of Cu(I) salt, cross-coupling reactions of acid chlorides with alkynylboronates giving rise to the corresponding conjugated ynones takes place readily in aprotic polar solvents such as DMI under neutral conditions
