A series of substituted diethyl arylphosphonates was synthesized by the microwave-assistedArbuzovreaction of triethyl phosphite and arylbromides in the presence of NiCl2 as the catalyst under solvent-free conditions in good yields. The resulting phosphonates were hydrolyzed to the corresponding arylphosphonic acids whose acidity was evaluated by physicochemical methods.
O–P–O pathway are extremely weak in 1, and the overall magnetic behaviors are dominated by the Mn2(salen)2 moieties. Single-molecule magnetic behavior is observed in 1. For compound 2, the AF interaction over the O–P–O bridge is much stronger. The coexistence of metamagnetism and single-chain magnetic behavior is observed for 2.
本文报道了O–P–O桥接的Mn 2(salen)2(salen = N,N'-双(水杨亚基)乙二胺)链化合物的第一个例子,即[Mn 2(salen)2(2-FC 6 H 4 PO 3 H)](ClO 4)·1 / 2CH 3 OH(1)和[Mn 2(salen)2(4-FC 6 H 4 PO 3 H)](ClO 4)(2)。膦酸酯配体在1中采用顺-反双齿桥接方式和一个顺-顺二齿在桥接模式2,源自异构膦酸酯配体。不同的桥接方式会导致Mn–O···O-Mn扭转角在O–P–O桥上发生显着变化,其中1和2分别为96.6和1.9° 。结果,通过O–P–O途径介导的反铁磁(AF)交换耦合极弱1,并且总体磁行为受Mn 2(salen)2部分支配。在1中观察到单分子磁行为。对于化合物2,通过O–P–O桥进行的AF交互作用更强。的metamagnetism和单链磁性行为的共存是观察2。
