Aluminum phosphinate and phosphates of salen ligands.
A new dealkylation reaction between organophosphate esters and Salen aluminum bromide compounds has been used to prepare three new aluminum salen compounds salen((t)Bu)AlOP(O)Ph2 (1) (salen = N,N'-ethylenebis(3,5-di-tert-butylsalicylideneimine)), [(MeOH)Alsalen((t)Bu)[OMePO2(O)]Alsalen((t)Bu)[OMePO2(O)]Alsalen((t)Bu)]Br (2), and [salpen((t)Bu)AlO]2[(BuO)2PO]2 (3) (salpen = N,N'-propylenebis(3,5...
متن کاملDissolution of amorphous silicon into solid aluminum
Metal films are known to dissolve crystalline semiconductors at temperatures well below the eutectic temperature. Dissolution and transport of common semiconductors in contact with Au films have been demonstrated at room temperature. 1 The solid AI metallization used in electronic devices is known to dissolve troublesome quantities of crystalline Si after heat treatment at 400oC.2 Metal films a...
متن کاملAmorphous calcium phosphates: synthesis, properties and uses in biomaterials.
This review paper on amorphous calcium phosphates (ACPs) provides an update on several aspects of these compounds which have led to many studies and some controversy since the 1970s, particularly because of the lack of irrefutable proof of the occurrence of an ACP phase in mineralised tissues of vertebrates. The various synthesis routes of ACPs with different compositions are reported and the t...
متن کاملThe Influence of Aluminum Phosphates on Graphite Oxidation
Composites based on graphite benefit a number of applications where low density, high-temperature strength and thermal shock resistant materials are needed. Carbon composites are currently used in applications such as thermal barriers for reentry vehicles and aircraft brakes[1,2]. However, despite the unique hightemperature properties of these composites, their susceptibility to gasification in...
متن کاملIonothermal synthesis and crystal structures of novel aluminum phosphates with in situ generated templates.
Protic ionic liquids (PILs) are a subgroup of ionic liquids and easily formed by proton transfer from a Brønsted acid to a Brønsted base. Two new crystalline aluminophosphates, [C5H16N2][Al(PO4)(HPO4)] (AlPO-PIL1) and [C5H16N2][Al2(OH)2 (PO4)2] (AlPO-PIL2), are successfully prepared for the first time from a protic ionic liquid, 3-dimethylaminopropylamine acetate. Their structures were determin...
