Abstract:
Among the large family of azaphospholes 1,2,4-diazaphospholes feature a particularly stable ring system. 3,5-Unsubstituted and 3,5-equally substituted 1,2,4-diazaphospholes and -diazaarsoles are best made from 1,3-bis(dimethylamino)-2-phospha/arsaallyl chlorides and hydrazines. This way four examples for single crystal X-ray structure investigations were prepared: The unsubstituted 1,2,4-diazaphosphole 2 and -diazaarsole 4, the N-substituted 1 -(2-pyridyl) 1.2.4-diazaphosphole 1, and the C-substituted 3,5-di-tert-butyl 1,2,4-diazaphosphole 3. They all possess planar rings with small angles at

Abstract:
N‑heterocyclic phospholes based on N,N-disubstituted 9,10-phenanthrenediimines were synthesized. Dimeric 1,3,2-diazaphospholes were obtained by reduction of 2-bromo diazaphospholes. In case phenanthrediimine with the most sterically hindrance, diphosphole can dissociate into phosphorus-centered radicals at record low temperatures (220 K) for this class. This behavior will allow the synthesis of new metal complexes and phosphorus-organic compounds under mild conditions.

New diazaphospholes and diazaphosphorinanes with formula were synthesized and characterized by 1H, 13C, 31P NMR and IR spectroscopy and elemental analysis. The structure of compound 1 has been determined by X-ray crystallography. A one-dimensional polymeric chain was observed in the crystalline lattice produced by intermolecular -P=O. . .H-N- and -C=O. . .H-N-hydrogen bonds. Compounds 1 and 2 contain five-membered rings and show high values for 2J(PNH) and 2J(P,C) coupling constants due to the ring strain. These constants are reduced seriously in compounds with six-membered rings. In compound

Abstract:
AbstractAliphatic diazo compounds display different reactivity towards the phosphaalkene 9: diazomethane, diazoethane and terf-butyl diazoacetate (10a-c) formally react with Si/P-insertion to give the hitherto unknown phosphaalkenes 12a-c. In contrast, 1-diazo-2.2-dim ethylpropane (10d) and diazotrimethylsilylmethane (10e) lead to the 1.2.4-diazaphospholes 15 and 17, respectively, if the primary products (11d , 14) are treated with sodium hydroxide in tetrahydrofuran. T he reaction of the nitrile oxides 18a-c with 9 yields the 1.2.4-oxazaphospholes 20a-c; the [3+2] cycloadducts 19a-c are assum
