Structure and photochemistry of di-tert-butyldiphosphatetrahedrane

Abstract

Di-tert-butyldiphosphatetrahedrane (tBuCP)2 (1) is a mixed carbon- and phosphorus-based tetrahedral molecule, isolobal to white phosphorus (P4). However, despite the fundamental significance and well-explored reactivity of the latter molecule, the precise...

Access to 1,2,3-triphospholide ligands by reduction of di-tert-butyldiphosphatetrahedrane

“…DFT calculations on A show that the HOMO lies higher and the LUMO lower in energy compared to P 4 . 11 This suggests that, in principle, A should be more easily reduced and oxidized. P 4 can be reduced at the potential E 1/2 = −1.55 V ( vs. bottom mercury in DMF).…”

“…6,7 This has inspired the study of the reaction chemistry of A–C , which has revealed some similarities, but also differences with respect to the chemistry of white phosphorus in particular. 3–5,8–14…”

“…1b). 10,11 Cyclobutadiene-type ligands are formed directly on the metal atom when A interacts with various low-valent Fe, Co and Ni complexes (Fig. 1b).…”
