Secondary phosphine oxides were prepared from R 1 PCl 2 and R 2 MgBr, followed by
hydrolysis. They were obtained in an enantiopure form by preparative chiral HPLC. These new …

We have measured the specific heat C (T) of the S= 3 2 Kagomé-lattice-containing compound
SrCr 9 p Ga 1 2− 9 p O 19. We find little field dependence of the low-temperature C (T), …
