MANUFACTURING METHOD OF BOROSILOXANE

PROBLEM TO BE SOLVED: To provide an industrially advantageous manufacturing method of borosiloxane, which is important as an electrolyte additive of a lithium ion battery or the like. SOLUTION: There is provided a boron compound having Lewis acid with index acceptor number of the Lewis acid of 60 to 110. There is provided a manufacturing method of borosiloxane represented by R5nB(OSiR1R2R3)3-n or the like by reacting hydrosilane represented by R1R2R3SiH or R1R2R4SiOSiR1R2H and a boronic acid derivative represented by R5nB(OR6)3-n or the like in the presence of a catalyst such as Tris (pentafluorophenyl) borane. R1 to R3 and R5 are each independently C1 to 12 alkyl or C6 to 12 aryl, R4 and R6 are each independently C1 to 12 alkyl, C6 to 12 aryl or H, and n is an integer of 0 to 2.

Triphenylsiloxy and Diphenylsiladioxy Derivatives of Boron

Tris(triphenylsiloxy)borane, phenyl bis(triphenylsiloxy)borane, 2-triphenylsiloxy-1,3,2-dioxa-borolanes, -borinanes, -borole and -borin and diphenyl bis(1,3,3,2-dioxa-borolane-2-oxy)silanes have been synthesized by various routes and the reactivity of Si-O-B linkage has been compared with that of Ge-O-B and Sn-O-B linkages.Tris(triphenylsiloxy)-borane reacts with acetyic acid by cleavage of Si-O bond to give triphenylsilyl acetate and boric acid. 2-Triphenylsiloxy-1,3,2-benzodioxaborole forms 1:1 addition complexes with pyridine, triethylamine and aniline.Condensation of diphenylsilane diol with boric acid, tri(isopropoxy)borane or phenyldihydroxyborane yields cyclic derivatives.
