Title:
PRODUCTION METHOD FOR ORGANOPOLYGERMANE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2011/102380
Kind Code:
A1
Abstract:
Disclosed is a production method for polygermane compounds having organic substituents (hereinafter referred to as organopolygermane compounds). Specifically disclosed is a production method such that organopolygermane compounds capable of forming a thin film that has a high refractive index can be produced with an improved yield. The method for producing polygermane compound having an organic substituent (R) is characterized by the reaction of an organohalogen represented by formula (1), a germanium tetrahalide and an alkali metal or alkaline rare earth metal. (1) R-X (In Formula (1), R represents an optionally substituted aliphatic hydrocarbon group with 1-20 carbon atoms, an optionally substituted alicyclic hydrocarbon group with 1-20 carbon atoms or an optionally substituted aromatic hydrocarbon group with 4-20 carbon atoms, and X represents a halogen atom.)
