The synthesis of 2,6,7‐trioxa‐1,4‐diphosphabicyclo[2.2.2]octane revisited: the synthesis of 2,6,7‐triphenyl‐2N,6N,7N‐triaza‐1,4‐diphosphabicyclo[2.2.2]octane and the synthesis of 1λ5‐phosphiranol

We report herein a reliable synthesis of P(OCH₂)₃P in a study aimed at understanding the factors that control its formation. We also report the serendipitous synthesis of the novel phosphiranol (CH₂)₂PO₂H and the synthesis of P(PhNCH₂)₃P in good yield. © 2001 John Wiley & Sons, Inc. Heteroatom Chem 12:114–117, 2001
