Other Hydrogen-Containing Bonds

Both the ability of silylenes to insert into Si-H bonds and their inability to insert into C-H bonds have been described in the previous sections. Several 

Both SiF2 and SiHj are capable of inserting into the S-H bonds of the P-H bonds of PH, or and the Ge-H bonds of GeH4 or 

Various kinds of silylenes including SiFj, SiMcj, Si(OMe)2, and SiMeOMe are noted for their ability to insert into the O-H bond of CHjOH, as illustrated in equation (94) using dimethylsilylene as an example. 

Among the insertion reactions, the Si-H, Si-0, and O-H insertions are the three which have been experimentally employed as means to trap silylenes formed by various kinds of methods.

Carbon forms a huge number of binary compounds with hydrogen. Three major categories of these compounds are alkanes, alkenes, and alkynes. An alkane has only single bonds between carbon atoms. The four simplest alkanes, which are shown in Figure 3-7. are methane, ethane, propane, and butane. An alkene, on the other hand, contains one or more double bonds between carbons, and an alkyne has one or more triple bonds between carbon atoms. Figure shows the structures of ethylene, the simplest alkene, and acetylene, the simplest alkyne. 

Various other reducing methods are employed for the conversion of (3-nitro alcohols to amino alcohols, namely, electrochemical reduction.107 The selective electrohydrogenation of ni-troaliphatic and nitroaromatic groups in molecules containing other groups that are easy to hydrogenate (triple bond, nitrile, C-I) are carried out in methanol-water solutions at Devarda copper and Raney cobalt electrodes (Eq. 6.55).107... 

Carbon, hydrogen, single bonds, and at least one -OH (may contain double and triple bonds and other structures)...
