Title:

BISPHOSPHITE AND PROCESS FOR PRODUCING ALDEHYDE COMPOUND WITH THE BISPHOSPHITE

Document Type and Number:

WIPO Patent Application WO/2005/090369

Kind Code:

A1

Abstract:

A bisphosphite represented by the following general formula (I): (I) (wherein Ar¹ and Ar² each independently represents optionally substituted arylene; R¹, R²,. R⁷, and R⁸ each independently represents optionally substituted alkyl, optionally substituted aryl, or optionally substituted heterocyclic group, provided that R¹ and R² or R⁷ and R⁸ may form a ring in cooperation with the oxygen atoms and phosphorus atom bonded to these; and R³, R⁴, R⁵, and R⁶ each independently represents hydrogen or alkyl, provided that the carbon atom having R³ and R⁴ and the carbon atom having R⁵ and R⁶ each is bonded in an ortho position to the Ar¹-Ar² bond); a process for producing an aldehyde compound which comprises using the bisphosphite and a compound of a metal in Groups 8 to 10; and a composition comprising the bisphosphite and a compound of a metal in Groups 8 to 10.
