K. Albrecht et al., [2.2]PARACYCLOPHANE-1-YNE - PREPARATION AND STRUCTURAL-ANALYSIS OF THE BIS(TRIPHENYLPHOSPHANE)PLATINUM COMPLEX, Chemical communications, (4), 1996, pp. 543-544
The first platinum complex of [2.2]paracyclophane-1-yne with a formal
triple bond in the two-carbon bridge is prepared and fully characteriz
ed by spectroscopic techniques as well as an X-ray crystal structure a
nalysis; accordingly, it is best described as a platinacyclopropene.
