A unique role in the addition of diazoalkane carbene to alkynes. In addition, the results of the theoretical investigation of Chapter 2 are exploited to show how changes in the phosphorus substituents can be used to fine tune regioselectivity of alkyne cycloadditions without modifying the substituents on the final product.
