Title:
METHOD OF SYNTHESIZING OLIGOMER COMPOUND WITH CROSS-COUPLING REACTION
Document Type and Number:
WIPO Patent Application WO/2007/105657
Kind Code:
A1
Abstract:
A method by which an oligomer compound is efficiently and precisely produced using the Suzuki-Miyaura cross-coupling reaction, which is highly versatile. This method of oligomer compound production is characterized by including: a step (i) in which a compound having a boric acid group or boric ester group and a compound having a leaving group and a masked boric acid group in the molecule are subjected to cross-coupling in the presence of a Group-10 transition metal catalyst to obtain a cross-coupling compound; and a step (ii) in which the masking group of the boric acid group is removed from the cross-coupling compound obtained in (i) above to obtain a cross-coupling compound having a boric acid group or boric ester group and this compound is subjected as a starting material to the step (i).
