The story of acyl phosphines: Synthesis, reactivity, and catalytic applications

“…The structure of 34 was also established by single crystal X-ray diffraction studies. [42][43][44] The synthesis of thiophene derived diketophosphanyl compounds 38 was reported by Minakata and coworkers. [45] Crossley and coworkers reported the first diphosphametacyclophane 39b (R = H) (Chart 3) via condensation of isophthaloyl chloride and MeP (SiMe 3 ) 2 .…”

Spin-Polarized Molecular Triplet States as Qubits: Phosphorus Hyperfine Coupling in the Triplet State of Benzoisophosphinoline

“…Recently, Minakata, − Baumgartner, and co-workers have described the phosphorus analogue of N -mesityl-1,8-naphthalimide ( M-NMI ), 2-mesityl-1 H -benzo­[ de ]­isophosphinoline-1,3­(2 H )-dione ( M-BIPD ) and its corresponding phosphorus oxide ( M-BIPDO ), Scheme . Nitrogen has a nuclear spin, I = 1, and a fairly small gyromagnetic ratio (γ N /2π = 3.077 MHz T –1 ), while phosphorus has a 100% natural abundance nuclear spin of I = 1/2 with a gyromagnetic ratio (γ N /2π = 17.235 MHz T –1 ) 5.5-fold larger than nitrogen’s.…”
