My son's aggressive behavior

I have 3 kids the oldest now almost 6 years old.  He is a challenge.

Since day one he was very alert never felt that he is an infant  he is very alert as I said extremely smart I have no doubt that he is a genius multi tasking could be concentrating on 5 or more thing at the same time without loosing control.  

He is very strong physically he is now in kindergarten, will be turning six in four month but he is stronger almost than 2nd or third grader he is even taller than second graders very handsome but very violent everything in his life goes to the extreme nothing about him I could call is  mild.  Nothing!

Since he was 10 month he started hitting our friends kids till now he is still hitting others for no reason he thinks that everything should be under his control on his own way he wants to be the boss of the house he want to take his teacher’s position and take decisions even if he plays it would be the roughest way he can not tolerate being said no to him.   So far he broke his arm twice.

I tried every possible way with him .  As his parents we are highly educated parents we both have masters degree in our fields mine is law so we tried to listen to observe to interact with him but did not work.  

I tried discipline and rewordings! Did not work, there is no way that I could put him on time out just no way.

I need to know what I should do for him in order to fix this I wanted to invest in his intelligence rather than worry about his behavior I am sure that he would be something one day if I could correct this matter, so please advice me.

First, you should arrange professional intervention and not try to manage this yourself. Second, he will require a systematic program of behavior management, and to this end you should read Lynn Clark's book SOS Help for Parents (see www.sosprograms.com). When you say that  "there is no way I could put him on time out" it is tantamount to surrendering your jurisdiction as his parent. Think about it. You are his parent. He is six years old. It is a problem when you think that you are unable to exercise a time out program with a six-year-old. It's time you re-claimed your authority and jurisdiction. Take a look at Dr. Clark's book and see what you think.
