Abstract
The metallacumulene [RhCl(=C=C=C=C=CPh2)(PiPr(3))(2)] (6) was prepared stepwise from [RhCl(PiPr(3))(2)](2) (1) and HC=CC=CCPh2OSiMe3 via the pi-alkyne complex 2, the diynylhydridorhodium(III) species 3, and the vinylidenerhodium(I) compound 4 as intermediates. The reaction of 6 w ith CH2N2 affords true isomers (A and B) of the square-planar rhodium( I) complex 7, in which the hitherto unknown hexapentaene H2C=C=C=C=C=C Ph2 is n-coordinated to the RhCl(PiPr(3))(2) fragment.
