A phosphine compound represented by general formula (1)
wherein
R′ and R″ independently are selected from alkyl, cycloalkyl and 2-furyl radicals, or R′ and R″ are joined together to form with the phosphorous atom a carbon-phosphorous monocycle including at least 3 carbon atoms or a carbon-phosphorous bicycle; the alkyl radicals, cycloalkyl radicals, and carbon-phosphorous monocycle being unsubstituted or substituted by at least one radical selected from the group of alkyl, cycloalkyl, aryl, alkoxy, and aryloxy radicals;
Cp
s
is a partially substituted or completely substituted cyclopentadien-1-yl group, including substitutions resulting in a fused ring system, and wherein a substitution at the 1-position of the cyclopentadien-1-yl group is mandatory when the cyclopentadien-1-yl group is not part of a fused ring system or is part of an indenyl group. These phosphines can be used as ligands in catalytic reactions.
一种磷化合物,其通式表示为(1),其中R'和R''独立地选择烷基,环烷基和2-呋喃基基团,或者R'和R''与磷原子结合形成至少包括3个碳原子的碳-磷单环或碳-磷双环;烷基基团,环烷基基团和碳-磷单环未经取代或被至少一种从烷基,环烷基,芳基,烷氧基和芳氧基基团组成的基团取代;Cps是部分取代或完全取代的环戊二烯-1-基基团,包括导致融合环系统的取代,当环戊二烯-1-基基团不是融合环系统的一部分或是一个茚基基团的一部分时,必须在环戊二烯-1-基基团的1位进行取代。这些磷化物可以用作催化反应中的配体。
