We study the L-infinity-formality problem for the Hochschild complex of theuniversal enveloping algebra of some examples of Lie algebras such asCartan-3-regular quadratic Lie algebras (for example semisimple Lie algebrasand in more detail so(3)), and free Lie algebras generated by a vector space ofdimension at least 2. We show that for these examples formality in Kontsevich'ssense does NOT hold, although some of them allow unconditioned deformability.We compute the L-infinity-structure on the cohomology given by homotopytransfer in certain cases.
