Diphenylsiliconediol (eo hape e tsejoang e le arylsilicondiol kapa DphOH) ke motsoako oa organosilicon.

 

Lintho tse tloaelehileng tsa diphenylsilicondiol li kenyelletsa:

1. Lintho tsa 'mele: kristale e se nang mebala e tiileng, e qhibilihang ka har'a metsoako ea lintho tse phelang tse kang ethanol le dimethylformamide.

2. Lintho tsa lik'hemik'hale: E na le electrophilicity e ntle 'me e ka kopana le metsoako e mengata e kang acid chloride, ketone, esters, joalo-joalo.

 

Tšebeliso ea mantlha ea diphenylsilicondiol e kenyelletsa:

1. Organic synthesis: electrophilicity ea eona e ka sebelisoa e le sesebelisoa sa condensation bakeng sa moloko oa esters, ethers, ketones le lihlahisoa tse ling tse lebisitsoeng ho organic synthesis.

2. Khemistri ea lintho tse bonahalang: Joaloka setsi sa organosilicon, se ka sebelisoa ho lokisetsa li-polymer tsa organosilicon le li-polymers.

3. Surfactant: E ka sebelisoa e le thepa e tala bakeng sa surfactant.

 

Mokhoa oa ho itokisa oa diphenylsilicondiol hangata o fumanoa ka karabelo ea phenylsilyl hydrogen (PhSiH3) ka metsi. Li-catalyst tsa tšepe tsa phetoho tse kang palladium chloride (PdCl2) kapa platinum chloride (PtCl2) hangata li sebelisoa ho arabela.
