## Abstract A new and efficient conjugate addition of trimethyl and triethyl phosphites to 3βΟβazidoacetylcoumarin **(****1****)** has been studied. The reaction proceeded smoothly at r.t. furnishing 1,2,3,4βtriazaphosphole coumarin derivatives **4a**, **4b** in βΌ75% yields. Linear substituted tria

Selective and efficient generation of alkyl radicals from alkenes as well as their addition to unsaturated ketones and aldehydes is reported. The method is based on a simple one-pot procedure involving the hydroboration of the alkene with catecholborane, followed by treatment with a catalytic amount
