Butadiene and methanol were telomerised in the presence of palladium catalysts with ligands containing 8‐diphenylphosphinochromane‐like substituents at phosphorus. MonoXantphos and monoSPANphos afforded the most active, stable and selective catalysts known to date under commercially relevant production conditions for 1‐methoxyocta‐2,7‐diene, the precursor to oct‐1‐ene.
丁二烯和甲醇在钯催化剂存在下进行端粒化,该催化剂的配体在磷中含有类似8-二苯基膦基铬烷的取代基。在商业相关的生产条件下,MonoXantphos和monoSPANphos提供了迄今为止最活跃,最稳定和选择性最强的催化剂,它们是辛烯-1-烯的前体1-甲氧基辛基-2-7-二烯。
