Abstract

Abstract The stepwise displacement of pip (= piperidine) from cis-(pip) 2 W (CO) 4 by 2- allylphenyldiphenylphosphine (adpp) affords cis-(η 3-adpp) W (CO) 4 (4) when the cis- (pip)(η 1-adpp) W (CO) 4 intermediate (2; adpp is P-bonded) is isolated and purified; directly, this reaction affords a 85/15 ratio of 1 to cis-(η 3-pdpp) W (CO) 4 (3; pdpp= 2- propenylphenyldiphenylphosphine). In contrast, it had been reported that displacement of ...
