Chapters 6-7

What type of oxidative addition can binuclear M complexes undergo?

1 electron oxidation

What is the order of selectivity for C-H oxidative addition of alkanes?

Primary > Secondary >> Tertiary

What type of CC bonds can undergo oxidative addition?

Strained CC bonds, such as cyclopropane

CC bonds when there is another L that can nucleophilically attack a C (ie: a Cp ligand)

Are alkenes with EWG substituents more or less reactive towards oxidative coupling?

More reactive as the C’s are more partial + positive

What is the relationship of pi-basicity of the M center and reactivity for oxidative coupling?

Strong pi-basicity —> higher reactivity for oxidative coupling

Does dissociation of sigma donor L’s increase or decrease reductive elimination reaction rate?

Increases reaction rate as it decreases the electron density of the M center

Are 4 coordinate d⁸ complexes reactive for reductive elimination?

No, must become 5 or 3 coordinate first

Is deuterated alkanes faster or slower for reductive elimination?

Deuterated alkanes are faster for reductive elimination
