The object of the present invention is to provide a new organic phosphorus ligand that can efficiently promote cross-coupling reaction to obtain the target substance at high yield, as well as a method of manufacturing such ligand whose steric characteristics and electronic characteristics can be fine-tuned and which can be used to cause cross-coupling reaction at high yield. As a means for achieving the aforementioned object, a phosphine compound expressed by General Formula (1) below is provided.
(In the formula, R
1
and R
2
are each independently a secondary alkyl group, tertiary alkyl group, or cycloalkyl group, while R
3
and R
4
are each independently a hydrogen, aliphatic group, heteroaliphatic group, aromatic group, alicyclic group, or heterocyclic group. Note that R
3
and R
4
have no phosphorus atom and that R
3
and R
4
are not both hydrogen at the same time).
本发明的目的是提供一种新的有机磷配体,可以高效地促进交叉偶联反应,以高产率获得目标物质,以及一种制造此类配体的方法,其立体特性和电子特性可以微调,并且可以用于高产率地引起交叉偶联反应。为了实现上述目的,提供了以下通式(1)所表示的膦化合物。(在公式中,R1和R2分别独立地为二级烷基、三级烷基或环烷基,而R3和R4分别独立地为氢、脂肪基、杂原子脂肪基、芳香族、脂环族或杂环族。请注意,R3和R4不具有磷原子,并且R3和R4不同时为氢)。
