A caged phosphine product is provided which can act as a ligand to form a metal complex. The metal complex can be used as a catalyst. The caged phosphine is a compound of formula (I) : or a salt thereof; wherein the groups R1 and R8 each independently represent: (a) no substituent group; (b) an oxide substituent group = 0; (c) a sulphide substituent group = S; (d) a selenide substituent group = Se; (e) a C1-C8 alkyl substituent group; (f) a C6-C8 aryl substituent group or a 5 to 8 membered ring hetero aryl substituent group; or (g) a Lewis acid substituent group; wherein the groups R2, R3, R4, R5, R6 and R7 each independently represent: (1) no substituent group; (2) a hydrogen substituent group; (3) a C1-C8 alkyl substituent group; (4) a C1-C8 alkoxy substituent group; or (5) a C1-C8 acyl substituent group; and wherein X represents a linking group that is selected from: (i) a C1-C12 alkylene linking group; (ii) an ether linking group; (iii) a C2-C6 alkenylene linking group; (iv) an ester linking group; (v)a (hetero) arylene linker; (vi) an amine linker; or (vii) a thioether linker.
