A tertiary phosphine compound of the formula (1):
wherein R¹ and R² represent independently from each other a hydrogen atom or a methyl group, or together form -CH=CH-CH=CH-; R³ is a hydrogen atom or a cycloalkyl group having 5 to 7 carbon atoms or a lower alkyl group which may be substituted with a halogen atom, a lower alkoxy group, a lower alkoxyalkoxy group or a phenyl group; X¹ is a halogen atom when both R¹ and R² are hydrogen atoms, or a hydrogen atom, a halogen atom, a lower alkyl group or a lower alkoxy group when at least one of R¹ and R² is not a hydrogen atoms; and m is an integer of 1 to 5, which is useful as a ligand of a transition metal complex that can catalyze various reactions.
式 (1) 的叔膦化合物:
其中 R¹ 和 R² 各自代表氢原子或甲基,或共同组成-CH=CH-CH=CH-;R³ 是氢原子或具有 5 至 7 个碳原子的环烷基或可被卤素原子、低级烷氧基、低级烷氧基烷氧基或苯基取代的低级烷基;当 R¹ 和 R² 都是氢原子时,X¹ 是卤素原子;当 R¹ 和 R² 中至少一个不是氢原子时,X¹ 是氢原子、卤素原子、低级烷基或低级烷氧基;以及 m 是 1 至 5 的整数,可用作过渡
