BEITRAEGE ZUR CHEMIE DES BORS. 132. 1-PHOSPHA- UND 1-ARSA-4-BORA-CYCLOHEXADIENE-2,5

The radical-initiated hydrophosphination and hydroarsination of diethylaminodialkynylboranes with C6H5EH2 (E = P, As) give the compounds 1-phospha- and 1-arsa-4-boracyclohexadienes-2,5 (IV and V, respectively).V is further reduced by C6H5AsH2 to its dihydro derivative.Rather narrow boundaries exist for a substitution chemistry at the BN bond in IVa/IVb: methanolysis yields the B-methoxy derivative which in turn can be converted into the t-butyl compound.Alkali metals cleave the exocyclic PC bond.The anion formed reacts with RX yielding P-alkyl derivatives.Chalcogens convert the phosphorus(III) derivatives into phosphorus(V) compounds.
