    • The olefinic carbon signals with a relatively large coupling constant have been assigned as the carbon at 3-position (adjacent to the phosphorus) in the case of related silylphosphinated alkynyl ketones.4 However, our HMQC and HMBC analyses of 3a, 3d, and 3i revealed that these doublet signals with relatively large coupling constants are certainly assigned as the carbon adjacent to Si, whereas the signals with relatively small coupling constants are assigned as the carbon adjacent to P.7,12
