Abstract:

Acyl phosphate monoesters are biomimetic acylation reagents that require coordination to metal ions to react with cis-diol substrates in water. With lanthanide catalysts, outcomes are compromised by (1) the competitive lanthanide-promoted hydrolysis of the acyl phosphate reagents as well as by (2) the high affinity of lanthanum ions for the phosphate monoester by-product. Based on analysis of the mechanism of the process, optimizing reaction conditions can selectively inhibit the lanthanum-promoted hydrolysis of acyl phosphate monoesters. Furthermore, using zinc salts and lead salts in place o

Abstract:

It was previously reported that diols dissolved in water (pH 8, EPPS buffer) react with benzoyl methyl phosphate (BMP) in the presence of lanthanide ions to form monobenzoyl esters. We have investigated the possibility of extending this process to include formation of esters of monosaccharides in water from lanthanide-catalyzed reactions with BMP. The combination of methyl-α-D-glucopyranoside and BMP in the presence of lanthanum trichloride gave selective monoacylation of the 2- and 6-hydroxyl groups in a ratio of 2:1. The likely mechanism involves preferential bisbidentate coordination of BMP

Abstract:

The mobilities of numerous polyols, sugars and methyl glycosides on ion-exchange resin thin-layer plates in the calcium and lanthanum form have been measured. Under these conditions, alditols which have a threo-threo sequence of hydroxy groups complex more strongly with lanthanum than with calcium, whereas methyl glycosides complex less strongly.

Abstract:

A series of lanthanum ion-doped titanium dioxide coatings have been prepared on the surface of 304 stainless steel by using sol-gel and dip-coating technology. The corrosion protection properties of the coatings were investigated by electrochemical measurements. It is found that the photogenerated cathodic protection property of the TiO2 coating is enhanced under illumination by doping with an appropriate amount of lanthanum ions. The results also indicate that the presence of lanthanum ions improves the corrosion protection property of the TiO2 coating without the photo effect attributed to t

Abstract:

Two types of lanthanide-containing derivatives of the 19-tungsto-2-arsenate(III) [As2W19O67- (H2O)]14− (As2W19) have been synthesized in mildly acidic aqueous media and characterized in the solid state. The ytterbium(III)-containing anion [Yb(H2O)2K(H2O)2As2W19O67(H2O)]10− (1) was formed by reaction of Yb3+ with the potassium salt of As2W19, while the lanthanum(III) derivative [La2(H2O)6As2W19O67(H2O)]8− (2) was formed by reaction of La3+ with the sodium salt of the trilacunary precursor [B-α-AsW9O33]9− (AsW9). The polyanions 1 and 2 crystallize as hydrated salts in the triclinic system, space

Lanthanide ions loaded TiO2encapsulated into Y zeolite catalysts were synthesized and used in sonocatalytic degradation of Amaranth dye in aqueous solution. The support zeolite Y was modified by different loading of Ti and La species using ion exchange method. The sonocatalytic reaction condition was carried out at 10 mg/L initial dye concentration, original pH, 1.5 g/L of catalyst loading with low ultrasonic frequency of 40 KHz. Different characterization techniques were used to reveal the physicochemical characteristics of the catalysts. Successful loading of TiO2and La/TiO2into zeolite Y wa
