5- phenyl chloride

Alternatives to the methyl chloride dkect process have been reviewed (31). Processes to make phenyl and ethyl siUcones have employed dkect-process chemistry. Phenyl chloride has been used in place of methyl chloride to make phenylchlorosilanes (15). In addition, phenylchlorosilanes are produced by the reaction of benzene, HSiCl, and BCl (17,31). EthylsiUcones have been made primarily in the CIS, where the dkect process is carried out with ethyl chloride in place of methyl chloride (32). Vinyl chloride can also be used in the dkect process to produce vinylchlorosilanes (31). Alternative methods for making vinylchlorosilanes include reaction of vinyl chloride with HSiCl or the platinum-catalyzed hydrosilylation of acetjdene with HSiCl. ...

If the potential leaving group is attached to unsaturated carbon, as in vinyl chloride or phenyl chloride, attack by nucleophiles is also extremely difficult, and these compounds are very unreactive in Sn2 reactions compared with simple alkyl halides. In these cases, the reason is not so much steric but electrostatic, in that the nucleophile is repelled by the electrons of the unsaturated system. In addition, since the halide is attached to carbon through an 5p -hybridized bond, the electrons in the bond are considerably closer to carbon than in an 5/ -hybridized bond of an alkyl halide (see Section 2.6.2). Lastly, resonance stabilization in the halide gives some double bond character to the C-Hal bond. This effectively strengthens the bond and makes it harder to break. This lack of reactivity is also tme for SnI reactions (see Section 6.2). 

Concerning the reactivity of the dianion 2 compared to that of the radical-anion 1, the first one behaves as a typical lithiating agent toward alkyl chlorides displaying an outer-sphere electron transfer reactivity profile no significant kinetic differences are found in the reaction of dianion 2 (as well as the radical-anion 1) with primary, secondary, tertiary and phenyl chlorides. On the other hand, a notable difference has been found in the reactivity of both species with several substrates and solvents .

VEEL spectra of surface phenyl groups have been obtained by ultraviolet photolysis of phenyl chloride on Ag(lll) at 300 K (211) and by thermal decomposition of phenyl iodide on Cu(lll) (212). The spectra are similar, and the strengths of the absorptions from the out-of-plane yCH modes, at 740 and 725 cm-1 respectively, show that the phenyl group is also more near to parallel than to perpendicular to the metal surfaces, again probably because of a combination of cr- and 77-bonding.

Aryl chlorides are more reluctant to participate in amination than most other aryl halides/pseudohalides. To tackle this problem, Caddick et al. examined the effect of palladium-N-heterocyclic carbenes as catalysts in rapid microwave-promoted reactions [87]. Para-tolyl and -anisyl chloride were reacted with aromatic and aliphatic amines in mostly good yields within 6 minutes of heating at 160 °C. Reactions using anisyl, tolyl or phenyl chlorides and aliphatic amines have also been reported by Maes et al. using a phosphine ligand and a strong base, which creates the desired products after 10 minutes of heating at 110-200 °C [88]. 

The reaction between phenyl cations and alkenols represents another example of a one-pot, tandem synthesis of cyclic ethers. Accordingly, 2-ben2yltetrahydrofurans are obtained by the addition of photogenerated phenyl cations to y-hydroxyalkenes. For example, 4-penten-l-ol (a terminal alkene) reacts with phenyl chlorides bearing EDGs under irradiation in polar protic solvents, suchasTFE oramixture MeCN/H20 (Scheme 10.57) [72],...
