Reddit mentions of Principles and Applications of Organotransition Metal Chemistry

I really love Principles and Applications of Organotransition Metal Chemistry, also known as "Collman and Hegedus"

You could try Collman's book, http://www.amazon.com/Principles-Applications-Organotransition-Metal-Chemistry/dp/0935702512 that was sort of the classic for a long time, but of course it's missing the past 20 years or so of progress.

Hartwig's more recent text book http://www.amazon.com/Organotransition-Metal-Chemistry-Bonding-Catalysis/dp/189138953X/ is sort of supposed to be the successor to Collman's book but it's extremely dense and a bit hard to just sit down and read.

This book http://www.amazon.com/Synthesis-Organometallic-Compounds-Practical-Inorganic/dp/0471970700 could be fun for you if your library has it.

Another classic: http://www.amazon.com/Problems-Solutions-Organometallic-Chemistry-Kegley/dp/0935702237 that one's fun to go through.

In all cases if you find examples, etc that are interesting to you, go to the references and read the original paper!

I would also definitely recommend starting to follow relevant published research, the ACS journal "Organometallics" being an obvious starting point (http://pubs.acs.org/journal/orgnd7)
