The ability of Lewis acids to coordinate to transition metals as σ-acceptor ligands was
recognized as early as in the 1970's, but so-called Z-type ligands remained curiosities until …

Up until recently, our understanding of the chemistry resulting from the combination of Lewis
acids and bases had not evolved much since Lewis' time. In large part, the formation of …

The ambiphilic species Al (C6H4 (o-PPh2)) 3 (2) was synthesized and fully characterized,
notably using X-ray diffraction. Species 2 exhibits pseudo-bipyramidal-trigonal geometry …

Publisher Summary Ambiphilic derivatives, also called “amphoteric derivatives”, are
polyfunctional compounds combining Lewis bases and Lewis acids. Such donor–acceptor …

Ambiphilic ligands have received considerable attention over the last two decades due to
their unique reactivity as organocatalysts and ligands. The iridium‐catalyzed C H …

A bis (phosphine) borane ambiphilic ligand,[Fe (η5‐C5H4PPh2)(η5‐C5H4PtBu {C6H4
(BPh2)‐ortho})](FcPPB), in which the borane occupies a terminal position, was prepared …

Gallant exchange: Upon coordination of phosphanyl gallane ligands to AuCl, both neutral
and zwitterionic complexes coexist. NMR spectroscopy provides direct evidence for the …

Coordination of Mes2PC (CHPh) AltBu2 to metal chlorides has been studied. Bridging P→
M–Cl→ Al coordinations were observed with Rh and Pd fragments, while chloride …

The direct electrophilic, nucleophilic, and amphiphilic allylations of allylic alcohol by use of a
palladium catalyst and organometallic reagents such as organoborane and organozinc has …

The monophosphino-boranes oi Pr2P (C6H4) BR2 (1: R= Ph and 3: R= Cy) and
diphosphino-boranes [o-R2P (C6H4)] 2BPh (5: R= Ph and 6: R= i Pr) readily react with CuCl …
