2PhSCH2Li*1.5N(CH2CH2)3N*0.5THF (I) and PhSCH2Li*2THF (II) can be isolated in a crystalline state from solutions of PhSCH2Li which have been obtained by metallation of thioanisole with BuLi/N(CH2CH2)3N and PhLi respectively, according to Corey and Seebach

supporting information; experimental part, p. 4576 - 4579 (2009/12/07)
3-Chloro-1-(phenylthio)propene, simply generated by chlorination of commercial allyl phenyl sulfide, is a versatile 3-carbon annulating agent for ketones and phenols.

Dibenzo[d,g][1,3]dioxocin-6-carboxylic acids substituted by methyl or ethyl or a moiety --CH2 CH2 -- at the 12-position and optionally substituted at other positions, such as methyl 4'-chlorospiro(cyclopropane-1,12'(12'H)-dibenzo[d,g][1,3]dioxocin)-6'-carboxylic acid, and their agriculturally acceptable esters, amides, and salts are useful for the control of undesirable vegetation. The 1,1-diarylcyclopropane intermediates required for the spirocyclopropane compounds can be prepared from appropriately substituted 1,1-diarylethene procursors by reaction with phenylthiomethyl lithium reagent.
Preparation of allylic lithium reagents with the allylic system partly incorporated into carbocyclic rings

, p. 143 - 152 (2007/10/02)
A new method is described for preparation of allylic type organolithiums in which two of the allylic system carbons form part of carbocyclic ring.It involves cleavage of the readily accessible allylic sulfides 1-phenylthiomethylcycloalkanes by the naphthalenelithium in tetrahydrofuran.Carbonation of the reagents has given mixtures of cycloalken-1-yl acetic acids and 2-methylecycloalkane carboxylic acids, the distribution of which is strongly dependent on the ring size; thus the proportion of cycloalkenyl acetic acid, the endocyclic olefinic product, increases sharply on going from C5 to C8 ring derivatives and then considerably less sharply on going from C8 to C10 at which point the carbonation reaction has a high selectivity.It is concluded that the site of attack in the allylic anion by CO2 is determined by the thermochemical stability of the product(s).
Synthesis of Aldehydes from Phenylthiotrimethylsilylmethane
Ager, David J.
, p. 1131 - 1136 (2007/10/02)
Phenylthiotrimethylsilylmethyl-lithium (4) reacts with alkyl halides to give 1-phenylthio-1-trimethylsilylalkanes (5), which can also be prepared by the addition of alkyl-lithium to 1-phenylthio-1-trimethylsilylethene (8), or from bis(phenylthio)acetals (11).The 1-phenylthio-1-trimethylsilylalkanes (5) can be converted into the corresponding aldehyde (15) by oxidation to the sulphoxide (13), thermal rearrangement, and hydrolysis of the resultant O-silyl thioacetal (14).
