Construction of {Mn[Ph2P(O)NP(O)Ph2]2} units with mono- and bi-pyridines: Syntheses, molecular structures, and spectroscopic properties of manganese(II) complexes with tetraphenylimidodiphosphinates

Treatment of [Mn(CH3COO)2·4H2O] with two equivalents of K[N(Ph2PO)2] in the presence of two equivalents of pyridine (py) or 4-tBu-pyridine (4-tBu-py) in MeOH–H2O afforded mononuclear complexes [Mn{N(Ph2PO)2}2(py)2]·2H2O (1) and [Mn{N(Ph2PO)2}2(4-tBu-py)2] (2), respectively. Interaction of [Mn(CH3COO)2·4H2O] with two equivalents of K[N(Ph2PO)2] in the presence of one equivalent of rigid dipyridyl-based ligand 4,4′-bipyridine (bpy) or trans-1,4-bis-(pyridyl)ethene (bpe) resulted in formation of one-dimensional linear polymeric chains [Mn{N(Ph2PO)2}2(μ-bpy)]n (3) and [Mn{N(Ph2PO)2}2(μ-bpe)·2CH2Cl2]n (5), respectively. Reaction of [Mn(CH3COO)2·4H2O] with each of one equivalent of K[N(Ph2PO)2] and K[Ph2PO2] in the presence of one equivalent of bpy afforded a polymeric complex [Mn{N(Ph2PO)2}2(μ-bpy)]n-[Mn2{N(Ph2PO)2}2(μ-Ph2PO2)2(μ-bpy)]n (4) which contains two independent one-dimensional linear polymeric chains. Self-assembly reaction of [Mn(CH3COO)2·4H2O], K[N(Ph2PO)2], bpy and bpe in a 1:2:1:1 ratio gave a dinuclear complex [Mn(bpe){N(Ph2PO)2}2]2(μ-bpy)·H2O (6). Self-assembly reaction of [Mn(CH3COO)2·4H2O], K[N(Ph2PO)2], and a flexible dipyridyl-based ligand 4,4′-trimethylenedipyridine (tmpy) in a 1:2:1 ratio gave a tetranuclear complex [Mn{N(Ph2PO)2}2(μ-tmpy)]4·2CH3OH·3H2O (7). All complexes are air-stable in the solid-state, and were well characterized by electronic, infrared and mass spectroscopies along with thermogravimetric analyses, and their molecular structures have been well established by X-ray crystallography.

2-Phenoxyethyldiphenylphosphine oxide as an equivalent of diphenylvinylphosphine oxide in nucleophilic additions

A facile method for the synthesis of β-functionalized ethyldiphenylphosphine oxides is developed based on readily available 2-phenoxyethyldiphenylphosphine oxide used as an equivalent of diphenylvinylphosphine oxide in the reactions of addition of different PH- and NH-nucleophiles in DMSO in the presence of KOH. The transformations of labile phosphine oxides of a general formula Ph2P(O)CH2CH2OR, where R = Ph, H, or Ph2P(O)CH = CH2, in aq.KOH/DMSO and solid KOH/DMSO systems are explored in the absence of nucleophilic reagents.

Reactivity of carbanions stabilized by two alpha phosphorus groups

The stabilized anion {[Ph2P(S)]2CH}- with lithium as counter cation 1a reacts with formaldehyde or benzaldehyde to give vinylidene phosphine sulfides [Ph2P(S)]2C=CHR, where R is H or Ph, respectively

Preparation of anhydrous organic acid salts

One-step process for preparing anhydrous, organic acid alkali or alkaline earth metal salts by contacting and reacting an organic or polymeric acid fluoride, anhydride or ester and an organic alkali or alkaline earth metal silanolate.

Process for the preparation of alkali metal and alkaline earth metal salts of diarylphosphinic acids

The alkali metal and alkaline earth metal salts of diarylphosphinic acids are prepared by reacting triarylphosphane oxides with alkali metal or alkaline earth metal hydroxides in a molar ratio of about 1:1 or 0.5, in the presence of water, under elevated pressure and at elevated temperature. In this manner, the alkali metal or alkaline earth metal salts of diphenylphosphinic acid are formed from triphenylphosphane oxide, which is the preferably used triarylphosphane oxide. Other salts or the corresponding free diarylphosphinic acids can, if desired, be obtained from the alkali metal and alkaline earth metal salts in a conventional manner. The products are principally intermediates in various fields.

Reactivite carbanionique de l'enchainement PV-CH2-CH2-S-. Application a la synthese d'un nouveau type de coordinats phosphoryles tetradentes

The tert-butyllithium metallation of compounds containing the group PV-CH2-CH2-SR proceeds by elimination of the group SR (R = H, CH3) followed by addition of tert-BuLi.Application of this addition-elimination reaction to functionalized phosphine-oxides Φ2P(O)CH2Z (Z = CN, COOEt) leads to the synthesis of γ-diphosphorylated compounds.These dissociate in basic medium following a mechanism which is the reverse of their formation as shown by treatment of the reaction mixture with p-chlorobenzaldehyde to give ethyl p-chlorocinnamate.
