- Long-range coupling between protons more than two carbon atoms apart is sometimes observed when bonds intervene. An example is found in 1-methoxy-l-buten-3-yne. Not only does the acetylenic proton, Ηa, couple with the vinylic proton Hb, it also couples with the vinylic proton Hc, four carbon atoms away. The data are: Construct tree diagrams that account for the observed splitting patterns of Ηa, Hb, and Hc.The following Walden cycle has been carried out. Explain the results, and indicate where Walden inversion occurs.Starting with [Pt(NH3)4]2+ or [PtCl4]2- and using the trans effect sequence, devise a rational procedure for synthesizing [Pt(py)(NH3)(NO2)Cl] with py and NH3 positioned trans to one another. Note, the fewer the steps, the better.
- The diasteromers of 4-t-butylcyclohexanol that you make can be distinguished by the splitting patterns of the proton attached to the carbon bearing th OH group. This is due to the fact that the H that is axial is a triplet of triplets because it is coupled to to sets of non-eqivalent protons, while the equatorial H is coupled to 4 equivalent hydrogens and is a pentet.
