Determine how many hydrogens the following compound has: C_9H_?NO, has one ring and three double bonds. Which of the following represents a hydrocarbon that contains one triple bond somewhere in the carbon chain? (a) alkane (b) alkene (c) alkyne (d) substi...
The eliminated P2 unit can be transferred to the terminal phosphide complexes P[triple bond]M(N[(i)Pr]Ar)3, 3-M (M = Mo, W), and [P[triple bond]Nb(N[Np]Ar)3](-), 3-Nb, to give the cyclo-P3 complexes (P3)M(N[(i)Pr]Ar)3 and [(P3)Nb(N[Np]Ar)3](-). These ...
aWe have already disclosed that the strained carbon–carbon triple bond of arynes could smoothly be inserted into metal- containing s-bonds (C–Sn,7 Sn–Sn8 or Si–Si9) in the presence of a palladium catalyst, giving various arylstannanes and arylsilanes in a straightforward manner. In view...

3c), complexes 3 and 4 each showed a single additional hydrogen bond (Supplementary Fig. S3), and complex 2 showed four extra hydrogen bonds (Fig. 3c). It turns out that only complex 2 is completely in line with all our experimental evidence. We therefore conclude that complex 2 ...
