Neue kettenf�rmige und cyclische Phosphane

A Systematic Survey of the Reactivity of Chlorinated N2P2, NP3 and P4 Ring Systems

“…The stability of differentP 5 H n (n = 0-7) structures has been investigated theoreticallya nd experimentally in an umber of publications. [64][65][66][67][68][69][70][71] Still, the bicyclo[1.1.1]pentaphosphane motif was considered only in as ingle publication, which identified the minimume nergy structure of P 5 H 3 as bicyclo[2.1.0]pentaphosphane (19 a). [68] This is in agreement with our own results, which show that bicyclo[1.1.1]pentaphosphane( 19 c)i si nf act the least favoured isomer of those previously discussed in the literature(Scheme 15, see also p. S40).…”

Phosphorus Hydrides and Phosphonium Compounds

“…The triphosphine P3H5 is isolated as a white solid also by the decomposition of diphosphine. Baudler and her co-workers 113 have identified a series of higher chain and cyclic phosphines by mass spectrometry from the higher boiling fraction of the product from the hydrolysis of Ca3P 2 or by the disproportionation of P2H4.…”

“…Seitdem in den H ydrolyseprodukten von Calciumphosphid und in den Therm olyseprodukten von Diphosphan eine unerw artete Mannigfaltigkeit von Phosphorhydriden massenspektroskopisch nachge wiesen werden konnte [2][3][4][5][6], gilt das besondere In teresse der Strukturaufklärung dieser Verbindungen. Wegen ihrer ausgeprägten Tendenz zur D ispropor tionierung sowie ihrer Unlöslichkeit und m angeln den Kristallisationsneigung entziehen sich die poly cyclischen Phosphorwasserstoffe PnH m (m < n) im allgemeinen einer direkten U ntersuchung.…”
