Titles differ between systems:

IPC: containing a metal-to-carbon bond; Metal hydrides

CPC: containing metal-to-carbon bond; Metal hydrides

Full Title

Full titles differ between systems:

IPC:

Preparation of hydrocarbons from hydrocarbons containing a smaller number of carbon atoms > by addition between unsaturated hydrocarbons > by oligomerisation of well-defined unsaturated hydrocarbons without ring formation > of alkenes, i.e. acyclic hydrocarbons having only one carbon-to-carbon double bond > Catalytic processes > with hydrides or organic compounds > containing a metal-to-carbon bond; Metal hydrides

CPC:

Preparation of hydrocarbons from hydrocarbons containing a smaller number of carbon atoms (redistribution reactions involving splitting C07C6/00) > by addition between unsaturated hydrocarbons > by oligomerisation of well-defined unsaturated hydrocarbons without ring formation > of alkenes, i.e. acyclic hydrocarbons having only one carbon-to-carbon double bond > Catalytic processes > with hydrides or organic compounds (C07C2/20 takes precedence) > containing metal-to-carbon bond; Metal hydrides
