Synthesis of mixed bis(alkenylcarbene) ditungsten complexes by sequential activation of dialkynols
摘要:
The synthesis of new bis(alkenylcarbene) ditungsten complexes 2a-b, 5a and 6a has been achieved from W(CO)(5)(THF), via activation of the dialkynol derivatives a and b. The reaction of 5a with piperazine affords a dissymmetric bis(aminocarbene) complex 7a. (C) 1997 Elsevier Science S.A.
