The aim of the subject is to acquire both theoretical and experimental knowledge of modern laboratory techniques. Among the performed experiments are cross-coupling reactions, photochemical reactions and other reactions that require handling of organometallic and hydride reagents, working under inert atmosphere using inert lines and septum techniques, working in a glovebox, working at low temperatures and with low-boiling liquids. The products obtained will be isolated by advanced separation techniques (vacuum distillation, crystallization and column chromatography) and their structure and purity will be determined by selected analytical methods (NMR spectroscopy, TLC, UV/VIS spectroscopy). Significant part of the course is devoted to the work on research project in the laboratory of student's tutor.

Students will attend a laboratory technique course (1st - 4th week of semester, entry 1-8 according to syllabus). Further work will be carried out in specialized laboratories (5th – 14th week of semester). Organization of specialized laboratories will be settled with the student's supervisor.
