Phosphole-based ligands in catalysis

Abstract

This review provides an overview of phosphole-based ligand families (monophospholes, multidentate hybrid phosphole ligands, diphosphole and 2,2′-biphosphole-based ligands) and their potential in metal- and organo-catalyzed reactions (asymmetric reactions included).

Marriage of heavy main group elements with π-conjugated materials for optoelectronic applications

“…128 This observation has been linked to light absorption stemming from π-π* transitions that are localized primarily within the butadiene moieties. Interestingly each of the reported plumboles by Saito showed photoluminescence at room temperature with emission maxima (λ em ) at 394 nm (137) and 404 nm (133). 128 it is unclear at this stage why blue-shifted emission maxima occur within these plumboles.…”

“…Briefly it is salient to cite some important review articles on phosphole and phosphabenzene chemistry, 129,130 including articles which describe the recent use of phosphole derivatives and their phosphine oxide analogues as light-emitting materials, 131 and as supports for metal-mediated catalysis. 132,133 As synthetic inorganic chemistry continues to grow as a field, new examples of heterocycles featuring arsenic, antimony and bismuth are surfacing in an increasingly frequent manner. 134 …”

A Calixarene‐Decorated Phosphole Oxide

“…[6] Fine tuning of their electronic and structural properties is frequently achieved by introducing conjugated, peripheral substituents on the phosphole core. [7] Despite intensive research efforts in this area, no phosphole that bears a conjugated calix-[4]arenyl unit has been reported to date.…”

[​4+2] versus [​2+2] Homodimerization in P(V) Derivatives of 2,4-Disubstituted Phospholes

“…Phospholes have found widespread interest in many areas, including catalysis, material sciences, and biological applications, due to the ready modification of their electronic, steric, and physicochemical properties and their different coordination modes to metals [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Among the various possibilities, changing the substituents or the substitution pattern on the phosphole ring or on the phosphorus atom can modify the stability and the aromaticity of these heterocycles [15][16][17].…”
