the crude product 2b with aqueous sodium carbonate solution led to the formation of the dinuclear carbonato-bridged complex [(11-Me-BPI)Pd}2(μ-CO3)] (3) which was characterized by an X-ray structure analysis. Reaction of 11-Br-BPI (1c) with a large excess (6 equiv.) of the acetylenes Me3SiCCH, Ph3SiCCH and PhCCH under Sonogashira conditions gave the alkynylated derivatives 11-(Me3SiCC)-BPI (4a), 11-(Ph3SiCC)-BPI
