The 2‐aryl‐3,4,5,6‐tetraphenyl‐1,2‐azaborinines 1‐EMe\(_{3}\) and 2‐EMe\(_{3}\) (E=Si, Sn; aryl=Ph (1), Mes (=2,4,6‐trimethylphenyl, 2)) were synthesized by ring‐expansion of borole precursors with N\(_{3}\)EMe\(_{3}\)‐derived nit

Heterocycles containing group 13 and 15 elements such as borazines are an integral part of organic, biomedical and materials chemistry. Surprisingly, heterocycles containing P and Al are rare. We have now utilized phosphaalumenes in reactions with al

In here we present the deoxygenation of the chalcogen oxides EO
In here we present the deoxygenation of chalcogen oxides EO2 (E = S, Se) with phosphanylidene-σ4-phosphoranes, also referred to as phospha-Wittig reagents. The reaction of DABSO (DABCO⋅2SO2) with R–P(PMe3) (R = Mes*, 2,4,6-tBu3-C6H2; MesTer, 2,6
