Novel chromium and tungsten mono- and multiethoxycarbene
complexes were synthesized from tris(4-
bromophenyl)amine and tri(2-furyl)phosphine substrates. A
comparative study between the amine and phosphine
multicarbene ...

Access to multicarbene complexes of a fused thienothiophene substrate was obtained by the use of the
tetrabrominated thieno[2,3-b]thiophene precursor in a lithium–bromide exchange reaction, followed by
nucleophilic attack ...
Van Jaarsveld, Nina Alletta; Liles, David C.; Lotz, Simon(Royal Society of Chemistry, 2010-05)
The activation of a section, or of all the carbons of thiophene by bromine in lithium–halogen exchange reactions, was implemented in a step-wise manner to facilitate the preparation
of novel multiple Fischer carbene-bearing ...
