✦ Synopsis

the mother liquors produce further 16 %. After being washed with cold ethanol and ether, the crystals are analytically pure. The proton magnetic resonance spectrum 141 gave the following data (numbers indicate p.p.m with tetramethylsilane as standard) : Si(CH& Si-CHz-Si S-CHI-C C-CH2-0 0.6 3.0 3.8 4.3

The spectrum was identical with those of specimens prepared according to 121 and 131.

In CC14 solution the singlet signal for the hydroxymethyl group is at T = 6.68 (3 H), but in dimethyl sulfoxide there arc two signals with relative areas 1:2 (OH;CH2). The signal for the vinyl protons occurs at T = 5.42 (2 H). Infrared spectrum: 880, 1640, 1770, 3070 (=CH2), 1035, 3360 (broad associ
