Successful oxidation of Ph2P(CH2)nPPh2 (n = 2, 4, 6) by tellurium leading to Ph2P(Te)(CH2)nP(Te)Ph2

The first successful syntheses of Ph2P(Te)(CH2) P-n(Te) Ph-2 ( n 2, 4, 6) via oxidation of Ph2P(CH2) nPPh2 by telluriumpowder are reported. The prepared compounds were characterized by elemental analysis, P-31 and Te-125 NMR spectroscopy, and single- crystal X-ray analysis.
