✦ Synopsis

Butyl-1H-1,3-benzazaphosphole (1a) reacts with tBuLi without addition to the P=C bond to form a lithium benzazaphospholide that affords the η 1 -(benzazaphospholide-P)tungsten(II) complex 2 upon reaction with [CpW(CO) 3 Cl]. It is sensitive to alcoholysis and to air oxidation yielding 1a and the P-oxo-benzazaphospholide complex 3, respectively. The (1,3-benzazaphosphole)pentacarbonyltungsten complex 4, obtained from 1b and [W(CO) 5 (THF)], reacts preferentially

## Abstract Phosphirano[1,2‐__c__][1,2,3]diazaphospholes 5, which feature a strongly pyramidalized phosphorus atom at a ring fusion position, were identified as a new type of phosphane ligands for transition metals. The derivatives 5a–c smoothly form W(CO)~5~ complexes, which are thermally quite st
