摘要：
The "selective" protonolysis of the beta-diketiminato calcium derivative [Ca{(NDippCMe)(2)CH}{N(Si-Me-3)(2)}(THF)] (Dipp = (C6H3Pr2)-Pr-i-2,6) with a selection of terminal alkynes has produced a series of dimeric acetylides [Ca{(NDippCMe)(2)CH}{mu-C equivalent to CR}](2), which have been characterized in solution and in the solid state. The asymmetry of the Ca-C-Ca' bridges is subtly dependent upon the extent of "side-on" (pi-type) interaction between the acetylide unit and the Ca' centers.
