单(1-甲基庚基)邻苯二甲酸酯 | Mono(1-methylheptyl)phthalate | 68296-97-9 | C16H22O4 | 278.348 |
苯酐 | phthalic anhydride | 85-44-9 | C8H4O3 | 148.118 |
The synthesis and pyrolysis of the methyl phthalate esters of diphenylmethylsilyl, t-butylsilyl, benzyldiphenylsilyl, and optically active 2-octanol yielded corresponding silyl ethers and phthalic anhydride. In the case of the latter compound, almost complete retention of configuration was observed about the asymmetric carbon atom. A mechanism is proposed for this rearrangement.
