    1-(2,4,6-Tri-tert-butylphenyl)-3-methylphosphole:  A Phosphole with a Significantly Flattened Phosphorus Pyramid Having Pronounced Characteristics of Aromaticity
    摘要:
    Single-crystal X-ray analysis of 1-(2,4,6-tri-tert-butylphenyl)-3-methylphosphole synthesized to test the effect of the strongly sterically demanding P-substituent on the geometry of the molecule, revealed that the phosphorus pyramid was drastically flattened; the normal out of plane angle of 65 degrees (formed between the P-substituent and the ring C-2-P-C-5 plane) was reduced to 45.9 degrees. Consistent with strong electron delocalization, the C-3-C-4 bond length was dramatically shortened relative to that for other phospholes, and the Bird index of aromaticity was 56.5, almost the equivalent of that in pyrrole (59). The phosphole ring, normally resisitant to electrophilic substitutions, underwent reaction with acetyl chloride-aluminum chloride, consistent with considerable cyclic electron delocalization.

  • Coordination chemistry and hydroformylation activity of platinum complexes containing 1-aryl-phospholes

    yl-phosphole (2) and 1-(2′,4′-di-tert-butyl-6′-methylphenyl)-3-methylphosphole (3)) with PtCl2(PhCN)2 was investigated by NMR spectroscopy. Significant differences in their reactivity towards PtCl2(PhCN)2 have been observed. Both cis-PtCl2(phosphole)(PhCN) and trans-PtCl2(phosphole)2 complexes were formed under normal reaction conditions. The corresponding reaction with the more basic 1-phenyl-3,4-dimethyl-phosphole

    Two (trialkylphenyl)phospholes (1 and 4) with significant heteroaromatic character due to the flattened P-pyramid underwent Friedel–Crafts acylation with acyl halides to afford 2-acylphosphole derivatives (e.g. 2 and 6, respectively); the 2-acyl-5-arylphosphole by-product 7 may have been formed by sigmatropic rearrangement through 2H-phosphole 9 or dibromophosphorane 12.

    Four different [4 + 2] cycloadditions were observed to take place in the equimolar mixtures of two different arylphosphole oxides 2a + 2b or 2b + 2c. In addition to the phosphole oxide dimers 3a-a and 3b-b, or 3b-b and 3c-c, the crossed cycloadducts 3a-b and 3b-a, or 3b-c and 3c-b were also formed in considerable portions. © 2001 John Wiley & Sons, Inc.

    Diels–Alder reaction of the title phospholes and N-phenylmaleimide afforded, surprisingly, a mixture of endo and exo fused cycloadducts with the P-aryl substituent anti to the double bond giving, after oxidation the corresponding P-oxides. The P-center of the exo ring fused P-oxides was found to be inverted under the conditions of the oxidation. The cycloaddition of triisopropylphenylphosphole with
