| Tricyclohexyl-cyclotriphosphane, (c-C6HnP)3 (1), is another relatively stable compound with a three membered phosphorus ring. It is produced in the reactions of (a) K2(c-C6HuP)4 with CH2CI2, (b) K2(c-C6HhP)4 with CS2, (c) C-C6H11PCI2 with sodium in dioxane. The following by-products are formed: (c-C6HhP)4CH2 (3), (c-CßHnP^ (2) and (c-C6H n P )4 in the reaction (a); mainly (c-CeHuP)4 in the reaction (b); (c-CeHnPjs (2) and (c-CeHnP)4 in the reaction (c). The P3 ring compound 1 and the P5 ring compound 2 can be isolated in a pure state. The oligomers (c-CeHnP)n, n —3, 4, 5, clearly are distinguished by the melting points, the molecular masses and by the 31P NMR and vibrational spectra. The 31P NMR parameters of 3 are reported. The cyclohexyl groups in 1, 2 and 3 are situated on both sides of the corresponding ring systems, giving rise to a maximum number of “trans” orientated neighboring substituents. | | | |
