The carbon NMR spectra of acetylene-metal pi complexes have been measured for a few examples of Pt(II),l Pt(O),' and COG complexes. Carbon spectra of olefin-silver(I) complexes have been reported.4-6 However, the factors affecting carbon chemical shifts are still the subject of debate. 7 In this com

REFERENCE DATA causes the electron density to be comparatively lower at C-3 and C-5 than at C-2 and C-4, so that the former signals resonate at lower fields. Distinction between the signals of the C-2/C-4 and C-3/C-5 pairs was achieved by comparing the C-H coupling patterns of 5 and 1. Compounds 1,
