We report the phospha-bora-Wittig reaction for the direct preparation of phosphaalkenes
from aldehydes, ketones, esters, or amides. The transient phosphaborene Mes* P═ B–NR2 …

This report provides an overview of the use of phosphaalkenes (C═ P) in syntheses of
various complexes. Going through successive complexes containing the d-block metals, we …

Heterofulvenes based on isolobal substitution of carbon fragments by (heavier) main group
motifs provide a rich source of structurally interesting building blocks with electronic …

The cycloaddition of 1-phosphabutadienes with AuI and PdII proceeds very differently when
the hydrogen substituent in the 3-position is replaced by methyl. Specifically, 1 …

The stepwise reduction of the highly contorted truxene‐based triphosphaalkene 1 using
KC8 led to the isolation of mono‐, di‐, and tri‐anionic species. The solid‐state molecular …

We explored coordination chemistry associated with valence isomerization between a
methylene (thioxo) phosphorane (MTP) and a thiaphosphirane. For this purpose, we …

We report the functionalization and deplanarization of truxenes using pnictaalkene
fragments. Selective introduction of one, two, or three Mes*‐Pn fragments provides up to …

The anionic polymerization of 1‐phosphaisoprene [Mes* P= C (Me)− CH= CH2 (E‐1)]
affords poly (1‐phosphaisoprene) 2 in high yield (75%). Concentrated solutions of polymer 2 …

This experimental and theoretical study illustrates how phosphaalkenes, which are isolobal
to alkenes, can utilize a variety of external triggers for molecular switching. The E/Z …
