Experimental:

The transformation from 9 to 10 was a one step reaction where methyl ketone (9) was treated with phosphazene base (3.0 eq) (schwesingers base) and nonaflorobutanesulfonyl flouride (1.3 eq) in dry DMF. This was then brought to room temperature for a total of twenty-six hours. Terminal Alkyne (10) was formed (92% yield).

*Note: 'd' in the mechcanism above indicated the experimental procedure stated above.
