In one aspect, phosphine compounds comprising three adamantyl moieties (PAd3) and associated synthetic routes are described herein. Each adamantyl moiety may be the same or different. For example, each adamantyl moiety (Ad) attached to the phosphorus atom can be independently selected from the group consisting of adamantane, diamantane, triamantane and derivatives thereof. Transition metal complexes comprising PAd3 ligands are also provided for catalytic synthesis including catalytic cross-coupling reactions.

The present invention is directed to a catalyst composition, comprising a Group 8 metal; and a ligand having a structure selected from the group consisting of:
1
wherein R, R′ and R″ are selected from the group consisting of H, a 1-10 carbon moiety, OR
1
, and NR
2
R
3
, wherein R
1
, R
2
, and R
3
are each individually a 1-10 carbon moiety, with the proviso that one of R, R′, or R″ is not H, and that R, R′, and R″ together do not form an adamantyl moiety; and
2
wherein L is selected from the group consisting of a 1-30 carbon moiety with a tertiary carbon bound to phosphorous The present invention is also directed to a method of forming carbon-carbon, carbon-oxygen, carbon-sulfur, and carbon-nitrogen bonds between substrates using the above catalysts.

(1-AdPH)2Fe2(CO)6 (11), whereas substitution of a PH proton in the chromium complex (1-AdPH2)Cr(CO)5 (1) by a diisopropylphosphino group led to the diphosphinecomplex (OC)5Cr(1-AdPHPiPr2) (15), which isomerized at elevated temperatures to (1-AdPHPiPr2)Cr(CO)5 (15a) with liberation of the diphosphine 1-AdPHPiPr2 (16). The crystalstructure of 15 is described; the PP bond length is 223.6(1) pm. 1-AdPH2 reacted
