Patent ID: 7166734

Claim:
A method of preparing an organometallic compound comprising the steps of: reacting a compound of the formula R 1 a′ M1 b′ Y 1 c′ wherein each R 1 is independently a (C 1 –C 10 ) organic radical, M1 is a Group IIB or IIIA metal, each Y 1 is independently a (C 1 –C 4 ) carboxylate or halogen, a′=0–2, b′ is the valence of M1, c′=1–3, and a′+c′=b′, with a compound of the formula R 2 x M2Y 2 3-x wherein each R 2 is independently a (C 1 –C 10 ) organic radical, M2 is a Group IIIA metal, each Y 2 is independently a (C 1 –C 4 ) carboxylate or halogen, x=1–3, in the presence of a tertiary amine, a tertiary phosphine or a mixture of a tertiary amine and a tertiary phosphine, wherein an electronegativity of M1≧ an electronegativity of M2.
