Resolution 242 is probably the most notorious failure, which among other things called for Israeli withdrawl from all territories occupied as a result of the 1967 war. It should be pointed out that the PLO rejected it too, albeit for rather different reasons. The Israelis also pretty much ignored Resolution 446 (dealing with "settlements" in the occupied territories), although attitudes have changed within Israel somewhat since the 'hawkish' attitude of the time. There are others, to varying degrees.
