- Synthesis, characterization and properties of titanium phosphonate clusters
-
Titanium phosphonate clusters were synthesized by the reactions of titanium tetraisopropoxide (Ti(OiPr)4) with arylphosphonic acids (ArPO3H2, Ar = Ph, 1-Nap, 4-MeOPh, 4-FPh, 4-ClPh, 4-BrPh, and 4-BrBn) and H2O in tetrahydrofuran (THF) at room temperature. [Ti4(μ3-O)(OiPr)5(μ-OiPr)3(O3PAr)3]·solv (Ar = Ph (1), 1-Nap (2), 4-MeOPh (3), 4-FPh (4), 4-ClPh (5); solv = thf for 1 and 2 or 2-propanol for 3–5) were isolated as new Ti4P3-type clusters, while Ti7(μ3-O)2(OiPr)6(μ-OiPr)6(O3PBnBr)6 (6) was isolated as a Ti7P6-type cluster. A co-crystal of Ti4P3- (7a) and Ti7P6-type (7b) clusters were obtained when 4-BrPhPO3H2 was used, and [Ti(OiPr)(acac)(O3PPh)]4 (8), a new cage cluster, was obtained when Ti(acac)2(OiPr)2 (Hacac = acetylacetone) was reacted with PhPO3H2.

- Synthesis and proton dissociation properties of arylphosphonates: A microwave-assisted catalytic arbuzov reaction with aryl bromides
-
A series of substituted diethyl arylphosphonates was synthesized by the microwave-assisted Arbuzov reaction of triethyl phosphite and aryl bromides 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.
