“…More recently, Manners and co-workers showed the addition of P 3 t Bu 3 to organic nitriles after activation of the three-membered ring by electrophiles to yield differently substituted 1-aza-2,3,4-triphospholenes in a click-type reaction (Scheme 1, G ),17,18 underlining the value of triphosphiranes as synthons in synthetic inorganic chemistry. Fragmentation of P 3 t Bu 3 was observed by Fenske and Ahlrichs in the reaction with Ni(CO) 4 , resulting in the formation of [Ni 5 (P t Bu) 3 (P 3 t Bu 3 )(CO) 5 ] with μ 4 - and μ 3 -bridging P t Bu ligands as well as a P 3 t Bu 3 chain, acting as a μ 4 (η 2 ,η 1′ ,η 2′′ ) ligand to three Ni atoms of the cluster 19…”

“…[11] They have seldom been employed as precursors for molecularc lusters and the few reporteda pproaches do not produce monomeric phosphinidene ligands buti nstead leave the cyclic framework intact.

We report a new family of nickel phosphinidene molecular clusters synthesized from the reaction of bis(1,5‐cyclooctadiene)nickel(0) ([Ni(cod)2]) with organocyclophosphine and trialkylphosphine. We found that [Ni(cod)2] cleaves the organocyclophosphine P−P bonds to generate phosphinidene groups, establishing the cyclic molecules as valuable precursors for making charge‐neutral molecular clusters passivated by two‐electron donor capping ligands. The formation of the cluster core structure is controlled by the bulkiness of the precursor and of the capping ligand. As a demonstration of this new cluster‐forming reaction, we describe three clusters with different core nuclearity and degree of ligation: Ni12(PMe)10(PEt3)8, Ni8(PMe)6(PMe3)8, and Ni8(PiPr)6(PMe3)6. In addition, we show that the larger cluster, Ni12(PMe)10(PEt3)8, can be used as a low temperature single‐source molecular precursor to the catalytically active nickel phosphide phase Ni2P.

“…The complex was synthesized from NiCl 2 and (P t Bu) 3 in the presence of P(SiMe 3 ) 3 . [ 75 ] In [Ni(P t Bu) 6 ] Ni is presumably zero‐valent and thus a synthesis starting from (P t Bu) 3 and Ni(CO) 4 was attempted. In this case, however, the cluster [Ni 5 (P t Bu) 3 (P 3 t Bu 3 )(CO) 5 ] (Scheme 31, bottom) was obtained with three P t Bu ligands and a P 3 t Bu 3 chain, which can be regarded as an intermediate in the formation of clusters with a Ni 8 core, such as III (Scheme 30, III) or [Ni 8 (PPh) 6 (CO) 8 ].…”

This Minireview outlines the synthesis and reactivity of homoleptic, cyclic oligophosphanes, which have been known for more than 150 years. We will discuss a variety of (PR)n (n = 3,4,5,6) species and outline approaches towards their syntheses in the first part of this review. Then the unique reactivity of these inorganic ring systems will be discussed in detail with a focus on recent findings within the last 20 years. First ring expansion reactions will be described, which are mainly restricted to cyclotriphosphanes. Secondly, ring fragmentation will be highlighted, including phosphinidene transfer reactions. Furthermore, cyclooligophosphanes can be functionalized while retaining the parent ring structures. As oligophosphanes offer multiple donor sites, in a last part the coordination chemistry of these species is highlighted. We hope that this Minireview will spark further interest in this underexplored class of compounds as reagents in inorganic and organic synthesis, as well as the design of new P‐containing materials.
