Notes: Eight new 2-phosphaindolizines 2 have been obtained by [4 + 1] cyclocondensation of 1,2-dialkylpyridinium halides 1 with PCl3. The X-ray structure analysis of 2a is consistent with the integration of the 1,3-azaphosphole ring in the 10π-aromatic system. The charge densities on phosphorus of various representatives as obtained by PM3 calculations correlate approximately with the 31P-NMR shifts. The mass spectral fragmentation of 2a resembles that of its nonphosphorus analog. © 1998 John Wiley & Sons, Inc. Heteroatom Chem 9:333-339, 1998
