high yield together with HSiR3. Reaction of CpFe(CO)2SiMes2H with LiAlH4 afforded only H2SiMes2. Labeling experiments using LiAlD4 gave the deuterated methylsilanes. These results proved that the hydrogen source for the methylgroup is LiAlH4. Furthermore, the reduction of CpFe(*CO)2SipTol2R‘ (*C = 13C enriched; R‘ = H, Me) produced *CH3SipTol2R‘ where the methylgroup introduced on Si was 13C-enriched
CpFe的量的处理(CO)2 SIR 3(CP =η 5 -C 5 H ^ 5 ; R 3 = pTol 2 Cl,pTol 2 H,pTol 2 Me,MePh(1-Nap)和(n -C 5 H 11)2 H; 在室温下用LiAlH 4在乙醚或THF中的1-Nap = 1-萘基)与HSiR 3一起以中等至高收率得到CH 3 SiR 3作为主要产物。CpFe (CO)2 SiMes 2 H与LiAlH 4的反应仅得到H 2 SiMes 2。使用LiAlD 4的标记实验得到了氘代甲基硅烷。这些结果证明了甲基的氢源是LiAlH 4。。此外,CpFe(* CO)2 Si p的还原Tol 2 R'(* C =富集13 C; R'= H,Me)产生* CH 3 Si p引入到Si上的甲基富含13 C的Tol 2 R' 。这些实验结果表明,羰基配体被LiAlH 4还原并与甲硅烷基基团偶联得到甲基硅烷。Cp

that the suggested method is applicable for the oxidation of organic alkylarene derivatives (Ar-CH3, Ar-CH2-R) to the corresponding acids and ketones (Ar-C(O)OH and Ar-C(O)-R), as well as hydride silanes ([Si]-H) to silanols ([Si]-OH). The possibility of synthesizing monomeric (methyl) and polymeric (siloxane-containing PET analogue, Sila-PET) esters based on 1,3-bis( p-carboxyphenyl)disiloxane was
