Phosphorus(III) ligands are pre-eminent in important areas of homogeneous catalysis (e.g. hydroformylation, hydrocyanation, C-C and C-N coupling reactions, olefin oligomerisation and metathesis, asymmetric hydrogenation) and many of these processes have found industrial applications. The facility and finesse with which P-ligands can be modified is one of the reasons for their popularity. Conventional P-ligands contain P-C, P-O or P-N bonds but the aims of this project are to stretch the boundaries of P-ligand space by exploring the use in homogeneous catalysis of ligands containing P-F, P-B and P=C bonds. The synthesis of these compounds has been developed recently but their applications in catalysis remains largely unexplored. The catalytic processes that will be investigated include hydroformylation using fluorophosphite ligands and dehydrogenation using pincer-ligand complexes. Phospha-alkene ligands have been extensively studied for academic interest but not as ligands for catalysis despite the great interest in the applications of N analogues (imines). Bis(phospha-alkenes) will be screened for a variety of catalytic reactions including methoxy-carbonylation.

磷（III）配体在均相催化的重要领域（例如加氢裂化、氢氰化、C-C和C-N偶联反应、烯烃低聚和复分解、不对称氢化）中是突出的，并且这些方法中的许多已经发现工业应用。P-配体可以被修饰的便利性和巧妙性是它们受欢迎的原因之一。传统的P-配体含有P-C，P-O或P-N键，但本项目的目的是通过探索含P-F，P-B和P=C键的配体在均相催化中的应用来扩展P-配体空间的边界。这些化合物的合成最近已经发展起来，但它们在催化方面的应用仍然很大程度上未被探索。将研究的催化过程包括使用氟亚磷酸酯配体的加氢和使用钳形配体络合物的脱氢。磷烯配体已被广泛研究的学术兴趣，但不是作为催化剂的配体，尽管在N类似物（亚胺）的应用有很大的兴趣。双（磷-烯烃）将被筛选用于各种催化反应，包括甲氧基羰基化。
