Reaktsii galogenidov selena s nepredel'nymi khal'kogenidami i silanami

V knige predstavleny sistematicheskie issledovaniya reaktsiy elektrofil'nogo prisoedineniya novykh reagentov - dikhlorida i dibromida selena k divinilkhal'kogenidam, dialkildietinilsilanam i -germanam s obrazovaniem predstaviteley novykh klassov geterotsiklov, soderzhashchikh kombinatsii atoma Se s atomami S, Si ili Ge. Digalogenidy selena - unikal'nye reagenty, kotorye v rezul'tate prisoedineniya po dvoynym uglerod-uglerodnym svyazyam privnosyat v tsiklicheskie addukty yarko vyrazhennyy ankhimernyy effekt atoma selena. Reaktsii prisoedineniya dikhlorida i dibromida selena k divinilsul'fidu ili divinilselenidu privodyat k obrazovaniyu ranee neizvestnykh shestichlennykh geterotsiklov - galogenzameshchennykh 1,4-tiaselenanov i 1,4-diselenanov, kotorye za schet effekta ankhimernogo sodeystviya preterpevayut samoproizvol'nye peregruppirovki s suzheniem tsikla, privodyashchie k obrazovaniyu novykh pyatichlennykh geterotsiklov - 2-galogenzameshchennykh 1,3-tiaselenolanov i 1,3-diselenolanov. Reaktsii elektrofil'nogo prisoedineniya digalogenidov selena k alkilzameshchennym dietinilsilanam i -germanam privodyat k obrazovaniyu zameshchennykh selenasila- i selenagermaful'venov.
