We prepared KH (P) by exposing K metal in an equal weight of melted paraffin to ∼1000 psi H 2 at 120 °C overnight. 5 The product after cooling was homogeneous by titration and appeared to be identical in every way to the KH (P) we had previously prepared 3 by washing the mineral oil off of commercial KH. ... With inexpensive KH now readily available, we have been exploring additional applications in organic synthesis. Alkyl ethers such as benzyl ethers are the ...
