 Title    Synthese und Kristallstruktur von l,l,l,3,3»3-Hexafluor-2-propylamino- l-thiooxamid +-Hexafluoro-2-propylamino- 1-thiooxamide"  
 Abstract    Dithiooxamide 1 reacts with hexafluoroacetone 2 at room temperature to yield 1,1,1,3,3,3-hexafluoro-2-propylamino-l-thiooxamide 3 and sulfur. The modes of formation of the bis(trifluoromethyl)-methyl group from hexafluoroacetone, the migra-tion of oxygen and the elimination of sulfur are not clear. Crystals of 3 are monoclinic, space group Cc, with a = 2865.3(13), b = 924.4(9), c = 702.9(6) pm, ß = 93.3(7)°. The structure was re-fined to R — 0.067 from 614 reflections.

 Title    Über die Reaktionen von Phosphanen MenP [OCH(CF3 )2] 3_" mit Hexafluoraceton Reactions of Phosphanes MenP[OCH(CF3)2]3-n with Hexafluoroacetone  
 Abstract    The stable phosphanes Me2POCH(CF3)2 and MeP[OCH(CF3)2]2 have been prepared and reacted with hexafluoroacetone yielding 1,2-oxaphosphetanes. The analogous reaction with Me2PF was carried out giving a 1 : 1 : 1 mixture of a 1,3,2-, a 1,3,4-dioxaphospholane, and a 1,2-oxaphosphetane. P[OCH(CF3)2]3 did not react with hexafluoroacetone. The new compounds were characterized by NMR, mass spectrometry and elemental analysis.
