The paper presents an analysis of the possibility of growing remontant type raspberry varieties in an annual culture in the climate of the northern regions, which solves the problem of shoots overwintering, both in decorative gardening and industrial plantings. The first stage of research in the collection nursery in the experiment on five remontant raspberry varieties regarding the requirements for soil and climatic conditions, resistance to diseases and pests, growth characteris-tics and individual development allows us to assess the development features of remontant raspberry varieties in the conditions of the Komi Republic. The collection nursery of remontant forms of raspberries of the Institute of Agrobio-technologies of the Federal Research Centre, Komi Science Centre, Ural Branch, RAS, was founded in 2018 and is represented by 5 varieties: Ruby necklace; Firebird, Elegant, Orange miracle, Hercules (St.). The studies were carried out according to the provisions of the standard method of field experiment during the growing seasons of 2018-2019. Agrometeorolo-gical conditions in 2018 were favorable for raspberry plants, in contrast to 2019. The unfavorable bal-ance of heat and humidity in the growing season of 2019 caused the end of the development of remontant raspberries at the stage of vegetative growth (Hercules variety) or flowering phase (4 varieties). Variety Orange miracle in the condi-tions of the Komi Republic is more susceptible to the risks of developing mycoses and damage by shoot gall midge. According to the results of two years of research, the Ruby Necklace variety showed good results in the formation of a certain number of shoots, resistance to pests and diseases, and the general condition of plants.

Triphenylstibin (I) reagiert mit den Hydroperoxiden (II) in Benzol bei Raumtemperatur im Molverhältnis 1:1 zu Triphenylantimonoxid (III) und den entsprechenden Carbinolen (IV), führt man die Reaktion im Molverhältnis (I):(II) = 1:3 durch, so entstehen die Triphenyl‐bis‐(organylperoxy)‐antimon‐Verbindungen (V).
