   Sammanfattning : The work presented in this thesis deals with metallacyclic late transition metal complexes, obtained by intramolecular Csp3-H activation, and the application of such compounds in catalysis. The new hemilabile P,O phosphines N-methyl-N-propionyl-2-(diphenylphosphino)benzylamine (DPPAM), o-(diphenylphosphino)benzoic acid ethyl ester (DPPES), o-(diphenylphosphino)benzoic acid methyl ether (DPPET) and ±-1-(2- diphenylphosphino)phenylethyl propionate (±-DPPMES) and the symmetrical diphosphorus donor ligands cis-1,3-bis[(diphenylphosphino)methyl]-cyclohexane (DPCY), cis-1,3-bis[(di-tertbutylphosphino)methyl]cyclohexane (DTBCY) and cis-1,3-bis[(di-isopropylphosphino)methyl]cyclohexane (DIPCY) have been synthesised, allowing the preparation of a range of new metallacyclic rhodium(III), iridium(III) and palladium(II) complexes.
