It is also called as Co-ordination polymerisation. Zeigler (1953) and Natta (1955) discovered that in the presence of a combination of transition metal halides like TCl4, ZnBr3 etc, with an organometallic compound like triethyl-aluminium or trimethyl-aluminium, stereospecific polymerisation can be carried out. Combination of metal halides and organometallic compounds are called Zeigler Natta catalyst.

Phosphine as ligand by Dr Geeta TewariGeeta Tewari
This presentation describes about the nature of phosphine ligands, bonding and reactions of metal phosphine containing complexes. Also explains the similarity and differences of phosphine ligand with NH3 and CO ligands.
Introductory PPT on Metal Carbonyls having its' classification,structure and applications.This is a basic level PPT specially prepared for UG/PG Chemistry students.
Organometallic Reactions and CatalysisRajat Ghalta
Organometallic compounds undergo a rich variety of reactions (oxidative addition, reductive elimination, cyclometalization, migratory insertion, carbonylation, hydrometallation hydrate elimination, etc ) that can sometimes be combined into useful homogeneous catalytic cycles. In this presentation, I have discussed organometallic reactions of particular importance for synthetic and catalytic processes like the oxo process (hydroformylation), heck coupling reaction, Wilkinson’s Catalyst
(Hydrogenation) etc.
This presentation will be helpful to beginners on chemical aspects of group theory. Also this ppt consists of videos on mirror plane symmetry and rotational axis of symmetry
