Synthesis and structure of 5-carbaphosphatrane

1-Hydro-5-carbaphosphatrane 4, the first 5-carbon analog of a phosphatrane, was synthesized. X-ray crystallographic analysis showed that it has a typical TBP structure and that it is a 10-P-5 phosphorane in a perfectly "anti-apicophilic" arrangement.

Chemistry of carbaphosphatranes

A 5-carbaphosphatrane and a 6-carbaphosphatrane were synthesized by utilizing triarylmethyl-type tetradentate ligands. Their structures were determined by X-ray crystallographic analysis to reveal that they have nealy ideal trigonal bipyramidal structures with a perfectly anti-apicophilic arrangement. 1JPH and 1JPC values of carbaphosphatranes were shown to be extraordinarily large as an apical coupling constant. The reactivities of carbaphosphatranes based on the tautomerization with their corresponding phosphonites were demonstrated in some reactions. Copyright Taylor & Francis Group, LLC.

Synthesis, structure, and bonding properties of 5-carbaphosphatranes: A new class of main group atrane

1-Hydro-5-carbaphosphatrane (1) and 1-methyl-5-carbaphosphatrane (2), the first 5-carbon analogues of phosphatranes, were synthesized by a demethylation reaction of cyclic phosphinate 3. X-ray analysis revealed that 1 has a typical trigonal bipyramidal st
