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.

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
Process for the preparation of alkali metal and alkaline earth metal salts of diarylphosphinic acids
-
, (2008/06/13)
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.
