Abstract
Attempted metallations of the expectedly acidic sulfonylamide (PSA) in the presence of the phosphine oxide HMPA all fail, giving instead the very stable 1:1 adduct PSA . HMPA; its solid-state structure consists of layers of PSA molecules linked by intercalated HMPA molecules, suc h aggregation resulting in particular from a large number of significa nt C-H ... O hydrogen-bonding interactions per PSA . HMPA unit.
