Abstract
síntese do catalisador de polimerização de metaloceno. um método sintético de pote único para produzir um ligante do tipo ciclopentadienila/fluorenila em ponte e o catalisador de polimerização ansa metaloceno correspondente. em uma etapa chave, um diânion de ciclopentadienida/fluoreneto é preparado combinando-se um composto de fluoreno, um composto de fulveno e pelo menos 2 equivalentes molares de kn(sime3)2 em qualquer ordem na presença de um solvente de éter sob condições ambientais. a reação do diânion de ciclopentadieneto/fluoreneto com um cloreto de metal de transição do grupo iv, seguida por alquilação, gera um catalisador de polimerização de metaloceno com rendimentos satisfatórios.
