Ge CH3 3C2H5 and Substituted Ethyl Derivatives

The compounds in this section are listed in Table 25. The ethyl-substituted derivatives have been arranged in the following way non-carbon-bonded substituents (designated X and Y) of one type (Nos. 2 to 11) or two types (Nos. 12 to 15), carbon-bonded groups on the C-1 atom and X groups on C-1 or C-2 (Nos. 16 to 25), and sp carbon atoms within the C2 chain and/or cyclic carbon-bonded groups (Nos. 26 to 54). 

Further information on compounds preceded by an asterisk is given at the end of the table. Explanations, abbreviations, and units on p. XI. 

Ge(CH3)3Br + Hg(CH2CHO)2 in C5H12 at 35 (6). along with Ge(CH3)30CH=CH2 (94) [23] a similar mixture obtained with Ge(CH3)3Cl [33] not separated from the vinyloxy isomer 

IR v(C=0) 1710 [23] 1705 as film there is no fast equilibrium between at least the vinyloxy and aldehyde forms based on H NMR between —46.5 and +82 [33] 

Ge(CH3)3C2H5 (Table 25, No. 1) has also been obtained in 17% yield by the reaction of CH3Li and the germylene Ge(C2H5)Cl (from Ge(C2H5)(H)Cl2 and CH30Li) in ether at —30°C to + 30°C, followed by treatment with CH3I [25].
