Preparation of group 12 and 13 metal compounds having low levels of oxygenated impurities

摘要

PROBLEM TO BE SOLVED: To provide an improved preparation method of group IIB and group IIIA compounds.;SOLUTION: The preparation method involves a process for reacting a compound represented by the formula: R¹_a'M1^b'Y¹_c' (wherein each R¹ is independently a 1-10C organic group; M1 is a group IIB or IIIA metal; each Y¹ is independently a 1-4C carboxylate or a halogen; a' is 0-2; b' is the valence number of M1; c' is 1-3; and a'+c'=b') with a compound represented by the formula: R²_XM2Y²_3-x (wherein each R² is independently a 1-10C organic group; M2 is a group IIIA metal; each Y²is independently a 1-4C carboxylate or a halogen; and x is 1-3) in the presence of a tertiary amine or a tertiary phosphine, provided that the electronegativity of M1 is equal to or higher than that of M2.;COPYRIGHT: (C)2006,JPO&NCIPI
