CURING ACCELERATING COMPOUND-SILICA COMPOSITE MATERIAL, METHOD FOR PRODUCING CURING ACCELERATING COMPOUND-SILICA COMPOSITE MATERIAL, CURING ACCELERATOR, CURABLE RESIN COMPOSITION, AND ELECTRONIC COMPONENT DEVICE

The present invention relates to a curing accelerating compound-silica composite material capable of giving excellent storage stability to a curable resin composition, which is obtained by subjecting one or more compounds selected from compounds represented by the general formula (I-1) below and partial condensates thereof to a sol-gel reaction in the presence of a curing accelerating compound and water; a curable resin composition comprising the same; and an electronic component device comprising a device sealed with the curable resin composition. [in-line-formulae]R1nSiR2(4-n)??(I-1)[/in-line-formulae]wherein n is 0 or 1; R1 is selected from a hydrogen atom and a C1 to C18 substituted or unsubstituted hydrocarbon group and may form a ring structure with R2; R2s represent a functional group reactive with a phenolic hydroxyl group, are selected independently from a halogen atom, a hydroxyl group, a C1 to C18 optionally substituted oxy group, a C0 to C18 optionally substituted amino group, and a C2 to C18 optionally substituted carbonyloxy group, all R2s may be the same or different from one another, and two or more R2s may be bound to each other to form a ring structure.

1,3-CARBANIONISCHE UMLAGERUNGEN: REAKTIONEN VON PHOSPHORSAEURE-o-HALOARYLESTERN MIT METALLEN ZU ARYLPHOSPHONSAEUREDERIVATEN

o-Bromoaryl esters of phosphoric acid react with magnesium to give arene phosphonic acid derivatives via intermediate Grignard compounds.Similar metallation rearrangement processes may be achieved in the case of o-chloroaryl esters if sodium is applied as

1,3-BENZOXAPHOSPHOLE-HETEROCYCLEN MIT PHOSPHOR DER KOORDINATIONSZAHL 2

The title compounds are formed in the reaction of o-phosphinophenole with N-arylimide chlorides of carbonic acids.The primary adducts of formimmonium chlorides, however, undergo -cycloaddition to furnish 1,3-diphosphetanes.A further way to 1,3-benzox
