METHOD FOR PRODUCING SILACYCLO MATERIALS

A method for producing silacycloalkanes by reacting an alkoxysilanc, R1ySi(OR2)4-y with a Grignard reagent, XMgR3MgX where each R1 is independently an alkyl group having 1 to 4 carbon atoms, an alkenyl group having 2 to 4 carbon atoms, a hydrogen atom, or CF3 each R2 is independently an alkyl group having 1 to 4 carbon atoms; y has a value of 1 or 2; R3 is selected from an alkylene group having 1 to 10 carbon atoms; and X is a halogen.

REACTIONS OF αω-BIS(BROMOMAGNESIO)ALKANES WITH HETEROCYCLIC ANHYDRIDES. A NOVEL SYNTHESIS OF FIVE AND SIX-MEMBERED 1-(o-AMINOPHENYL)CYCLOALKANOLS AND 1-(2'-AMINO-3'-PYRIDINYL)CYCLOALKANOLS

Isatoic anhydrides and azaisatoic anhydrides are converted by reaction with 1,4-bis(bromomagnesio)butane and 1,5-bis(bromomagnesio)pentane into the corresponding 1-(o-aminophenyl)cycloalkanols and 1-(2'-amino-3'pyridinyl)cycloalcanols.
