CA 2295251

This invention describes a process for covalently coupling organic compounds which comprises reacting an olefinic compound having a halogen or halogen-like substituent at a coupling position with a diboron derivative in the presence of a Group VIII metal catalyst and a suitable base. The invention also describes a process for preparing alkene borate intermediates comprising reacting an olefinic compound having a halogen or halogen-like substituent with a diboron derivative in the presence of a Group VIII metal catalyst and a suitable base.

L'invention concerne un procédé de couplage covalent de composés organiques, consistant à faire réagir un composé oléfinique possédant un substituant halogène ou de type halogène au niveau d'une position de couplage, avec un dérivé diborique, en présence d'un catalyseur à base d'un métal du groupe VIII et d'une base appropriée. L'invention concerne également un procédé de préparation d'intermédiaires de borates d'alcènes consistant à faire réagir un composé oléfinique possédant un substituant halogène ou de type halogène, avec un dérivé diborique, en présence d'un catalyseur à base d'un métal du groupe VIII et d'une base appropriée.
