Hi
I have two cyclometallions. The Ruthenium cyclometallion I have attempted to draw the mechanism for. I was wondering if it was correct. But I count 16 electrons for the product.

The addition of the arylphosphite I do not understand, in the product we produce ( the 5 membered ring), I count only 15 electrons, is this not unstable? If anyone would be kind enough to draw the mechanism for this particular reaction, that would be much appreciated. What is being added via oxidative addition in this case, I only see the C of the pehnyl ring

THanks

Sorry, made an error in my first post.

I count 18 electrons for the Ru complex ( I assume that each ligand from the cycloaddition, which are, the hydride and C of a benzene are two electron donors).

I only count 17 for the Co complex though
