For the first time, 1-and 2-adamantyllithium, 1-diamantyllithium, 3, 5, 7-trimethyl-l- adamantyllithium, 1-twistyllithium, 3-methyl-7-noradamantyllithium, 1-triptycyllithium, and 3- homoadamantyllithium have been directly synthesized from the reaction of an organic halide and lithium metal. By use of certain experimental parameters, the phenomena at the metal- solution interface are controlled, thereby resulting in exceptionally high yields of this new ...
