A highly strained polycyclic alkyne with a cage structure, 4-homoadamantyne 2, has been generated and trapped with diphenylisobenzofuran and by complexation with Pt(0); X-ray crystallography of the Pt(0) complex 4 and molecular mechanics calculations for 2 indicate that the molecular strain in 2 and in 4 is nearly as large as that in cyclohexyne and in its Pt(0) complex.
