The direction of the addition of the hydrocarbonyl to the olefin may, within certain limitations, be influenced by varying the reaction temperature and CO partial pressure or by replacing CO ligands by other com-plexing agents. As shown by R. F. Heck and D. S. Breslow [35, 759] and by Y. Takegami et al. [58], the olefinic compound itself may exert a strong influence. Under certain conditions the hydrocarbonyl may even be forced to react in the acid form. Thus, at low temperatures isobutylene reacts with hydrocarbonyl to form trimethylacetyl cobalt carbonyl [35, 759] nearly exclusively. The acyl compound could be trapped with triphenylphosphine. It reacted with methanol to form methyl trimethylacetate. 

On the other hand at higher temperatures isobutylene reacts to yield methyl-3-methylbutyrate as main product with hardly any methyl trimethylacetate being formed at all.
