The radical-initiated hydrophosphination and hydroarsination of diethylamino-dialkynylboranes 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
用C 6 H 5 EH 2(E = P,As)进行的二乙基氨基-二炔基硼烷的自由基引发的加氢磷酸化和加氢砷化,分别得到化合物1-phospha-和1-arsa-4-boracyclohexahexanesnes-2,5(分别为IV和V) )。V进一步被C 6 H 5 AsH 2还原成其二氢衍生物。对于IVa / IVb中BN键的取代化学而言,存在较窄的边界:甲醇裂解生成B-甲氧基衍生物,而该B-甲氧基衍生物又可以转化为叔丁基化合物。碱金属裂解环外PC键。形成的阴离子与RX反应生成P-烷基衍生物。硫属元素将磷(III)衍生物转化为磷(V)化合物。
