Room-temperature hydrohydrazination of terminal alkynes catalyzed by saturated abnormal N-heterocyclic carbene-gold(I) complexes

Metal-free synthesis of 3,5-disubstituted 1H- and 1-aryl-1H-pyrazoles from 1,3-diyne-indole derivatives employing two successive hydroaminations

The uncatalyzed synthesis of 3,5-disubstituted 1H- and 1-aryl-1H-pyrazoles derived from 1,3-diyne indoles was successfully carried out in PEG 400. The scope and limitations of the reaction were studied.

A simple access to transition metal cyclopropenylidene complexes

The first example of a BAC–Cu complex, its outstanding catalytic activity in Click chemistry and its use as a carbene-transfer reagent to easily access Au-, Pd–, Ir– and Rh–BAC compounds are reported.

Activation of boryl-, borylene and metalloborylene complexes by isonitriles

One or several isonitriles can insert into metalloboryl and metalloborylene complexes to afford cyclic or spiro compounds with bonding controlled by the electron count at the metal and in the ring.
