Bifunctional polymethylenediisocyanates O:C:N(CH2)nN:C:O (n = 4, 6) react with the extremely electron-rich 8\textgreek{p} electron heterocycle 1,4-bis(trimethylsilyl)-1,4-dihydropyrazine 1 under insertion of the heterocumulene functions into the N-Si bonds. Of the expected electron-rich oligomeric structures the first isolated products are presented, including the cycle structure of the 1:2 addn. product between OCN(CH2)4NCO and 1. This product contains two trimethylsilylurea functionalities.
