Die Fluorphosphane Ph2PF (1), PhOPF2 (2), C5H10NPF2 (3), (Et2N)PF2 (4) und (Et2N)2PF (5) reagieren mit Me3SiN3 uber die Zwischenstufe der Azidophosphane R3−nP(N3)n zu Oligo- und Polyphosphazenen, (RR′PN)n. (iPr2N)2PF (6) wird dagegen durch Me3SiN

The reaction of phosphorus (III) halides, R′3−n PXn (X [dbnd] F, C1), with silyl azides, R3SiN3, are described. N-silyated halo- phosphazenes, R'3−n PX [dbnd]N[sbnd]SiR3, are only obtained with fluorophosphanes having bulky substituents. Usuall

Azidophosphanes are versatile reactants in the Staudinger reaction. The azides Cl2PN3 (1), (Et2N)ClPN3 (2), and (Et2N)2PN3 (3) react with phosphanes to give the N-phosphanyl phosphazenes 4–10. (Et2N)P(N3)2 is oxidized by PhN3 yielding (Et2N)P(N3)2N

Hexaploid wheat (Triticum aestivum) contains triplicated genomes derived from three distinct species. To better understand how different genomes are coordinated in the same nucleus of the hexaploid wheat, we globally compared gene expression of a syn

The genomic constitution of Aegilops cylindrica Host (2n = 4x = 28, DcDcCcCc) was analyzed by C-banding, genomic in situ hybridization (GISH), and fluorescence in situ hybridization (FISH) using the DNA clones pSc119, pAs1, pTa71, and pTA794. The C-b
