## Abstract Polybutadiene‐ol was synthesized by solution radical polymerization of 1,3‐butadiene in the presence of hydrogen peroxide as initiator and 2‐propanol as solvent. The ratio of initiator to monomer molar concentration, [I~0~]/[M~0~], was varied while temperature, reaction time and the typ
## Abstract C~2~ deprotonation of 1,3‐dibutylperimidinium bromide (**1a**) with sodium hydride and a catalytic amount of potassium __tert__‐butoxide in dry THF led to the formation of the exceptionally inert tetraaminoalkene **2a**. In contrast, isostructural tetrakis(2‐methoxyethyl)‐tetraaminoalke
