Acetic acid mediated synthesis of phosphonate-substituted titanium oxo clusters

New phosphonate/acetate-substituted titanium oxo/alkoxo clusters were prepared from Ti(OiPr)4 and bis(trimethylsilyl) phosphonates in the presence of acetic acid, which served to generate water in situ through ester formation. The process led to clusters with a higher degree of condensation than in previously known phosphonate-substituted titanium oxo clusters. The clusters [Ti6O4(OiPr)10(OAc)2(O 3PR)2] (OAc = acetate) were obtained for a large variety of functional and non-functional groups R under a range of reaction conditions. This cluster type, which is also retained in solution, therefore appears to be very robust. Two other clusters, [Ti5O(OiPr)11(OAc)(O 3PCH2CH2CH2Br)3] and [Ti5O3(OiPr)6(OAc)4(O 3P-xylyl)2], were only isolated in special cases. Several acetate/phosphonate-substituted titanium cage compounds were obtained from the reaction of titanium isopropoxide with bis(trimethylsilyl) phosphonates in the presence of acetic acid as water generator.

NONAQUEOUS ELECTROLYTE SOLUTION CONTAINING SILYL ESTER GROUP-CONTAINING PHOSPHONIC ACID DERIVATIVE, AND LITHIUM SECONDARY BATTERY

The present invention provides a non-aqueous electrolyte solution which contains a silyl ester group-containing phosphonic acid derivative.

Dealkylation of phosphonate esters with chlorotrimethylsilane

Chlorotrimethylsilane completely dealkylates phosphonate esters at elevated temperature in a sealed reaction vessel. These conditions are tolerated by a variety of functional groups and lead to high conversions of dimethyl, diethyl and diisopropyl phosphonates to their corresponding phosphonic acids.
