Ni(pme3)4 reacts with phosphites , p(or)3 to produce ni(pme3)3(p( (a) what geometry do you expect for these nickel compounds (b) based on the 18 electron rule, what mechanism would you expect for the reaction the rate constant for the reaction is identical with different r groups in the phosphite. based on this result do you think the reaction follows a dissociative, associative or interchange mechanism?
