| Description
| - The interaction between POCl3 or POBr3 and pyridine or DMAP has been reinvestigated to clarify the discrepancies between previously published results concerning the Lewis acidity of phosphoryl halides and their behavior toward pyridine bases. The obtained results show that POCl3 virtually does not react with pyridine, while it does with 4-(dimethylamino)pyridine (DMAP), even in SO2 solution, to yield an ionic compound [(DMAP)2PO2]Cl.3SO2 (1.3SO2). Its recrystallization from acetonitrile gives [(DMAP)2PO2]Cl.CH3CN (1.CH3CN). The POBr3 reacts readily with both DMAP and pyridine forming the analogous tribromides, [(DMAP)2PO2]Br3 (2) and [(py)2PO2]Br3 (3),respectively. The crystal structures of 1.CH3CN,1.3SO2, 2, and 4 revealed that all four compounds are ionic containing the distorted tetrahedral cations [(DMAP)2PO2]+ and [(py)2PO2]+ .

- Za účelem objasnění rozporů mezi dříve publikovanými údaji o Lewisově kyselosti halogenidů fosforylu a jejich chování vůči pyridinovým bazím, byly znovu studovány reakce mezi POCl3, resp. POBr3, a pyridinem nebo DMAP. Výsledky studia ukazují, že POCl3 skutečně nereaguje s pyridinem, zatímco reaguje se 4-(dimethylamino)pyridinem (DMAP), dokonce i v roztoku v kapalném SO2, za vzniku iontové sloučeniny [(DMAP)2PO2]Cl.3SO2 (1.3SO2). Její rekrystalizace z acetonitrilu vede k [(DMAP)2PO2]Cl.CH3CN (1.CH3CN). POBr3 snadno reaguje jak s DMAP, tak i s pyridinem, za tvorby obdobných tribromidů, [(DMAP)2PO2]Br3 (2), resp. [(py)2PO2]Br3 (3). Krystalové struktury 1.CH3CN,1.3SO2, 2, a 4 prokázaly, že všechny čtyři sloučeniny mají iontovou strukturu, která obsahuje deformované tetraedrické kationty [(DMAP)2PO2]+ a [(py)2PO2]+. (cs)
