Description

Изобретение относитс  к области получени  кремнинсодержандих гетероциклических соединений типа 1-сила-2,3-бе}13офеналена, в которых атом кремни  включен в ароматическую циклическую систему. Соединение имеет следующую структурную формулуThis invention relates to the field of production of silicon-containing dehydrated heterocyclic compounds of type 1-strength-2,3-b} 13-phenenalene, in which the silicon atom is included in the aromatic ring system. The compound has the following structural formula

Соединение  вл етс  нервым нредставителем нового класса кремни11содержащих гетероциклических соединений, в которых кремний входит в шестичленный цикл и св зан обеими валентност ми с ароматическими атомами углерода .The compound is the nerve agent of a new class of silicon-containing heterocyclic compounds in which silicon enters a six-membered cycle and is bound by both valences to aromatic carbon atoms.

1,1 -Дихлор-1 -сил а-2,3-бензофенален  вл етс  кремнийорганическим мономером и способен к гидролизу по св з м Si-С1 с последующей ноликонденсацией. Он может быть использован в качестве одной из компонент синтеза силоксаповых жидкостей, смол, каучуков и теплоносителей с повышенной термической стабильностью.1,1-Dichloro-1 -syl a-2,3-benzophenylene is a silicone monomer and is capable of hydrolysis via Si-C 1 bonds, followed by condensation.
