Hoppe and Gonschorrek also reported the interesting formation of an enyne structure [137]. Deprotonation of allenyl carbamates 242 bearing a benzoyloxy group caused a 1,4-elimination of lithium benzoate, furnishing 1-alkynyl carbamates 243 in moderate to good yield (Scheme 8.63). 

PE layers were formed in Z-cut LiNbOs and LiTaOs congruent crystals by using a variety of proton sources, such as benzoic acid - pure (CeHsCOOH) or diluted with lithium benzoate (CeHeCOOLi) pyro-phosphoric acid (H4P2O7), etc. The plates were immersed in the acid melt for various periods of time (up to 8 h in the case of LiNbOs and up to 42 h for LiTaOs substrates) at a temperature in the range of 200 - 240°C. Some of the samples were subsequently annealed at temperatures up to 420°C for periods of time varying from 10 min to 2 h. 

Methods (a) Diethylethoxymagnesium malonate and an acid chloride (b) nitrile and a Grignard reagent (c) dimethylcadmium and an acid chloride and (d) lithium acetate or lithium benzoate and a 2-benzo[6]thienyllithium. 

Similarly, when methylenecyclopropane was treated sequentially with butyllithium and lithium benzoate, l-benzoyl-2-methylenecyclopropane (7) was obtained in 81% yield.Other examples can be found in refs 375, 376, 804, 838, 912, 913, 920. 

The carbamate-stabilized allenyl anion was shown to have moderate configurational stability. Thus, when the 4-benzoate derivative of the allenyl compound is lithiated, 1,4-elimination of lithium benzoate. occurs to form the very reactive 3-alken-l-ynyl carbamates stereospecifically (Scheme 34). ... 

Lithium benzoate. Added lithium benzoate to complex dissolved in THF at 35 °C, heated to reflux for 25 min, cooled, stirred 1 hr before hydrolysis hydrolyzed recrystallized from ethanol mp 56°C (lit mp 60°C) 44%, benzylphenyl ketone (36). 

Selected bond distances of alkali metal chalcogenocarboxylates are collected in Table 1. The molecular structure of lithium benzoate 2 is a centrosymmetric dimer with an eight-membered ring composed of coplanar C, O, and S atoms and tetrahedrally-coordinated Li atoms above and below this plane, where the C-0 [1.246(2) A] and C-S distances [1.704(2) A] show considerable multiple bond character [6]. From an ab initio optimization calculation on a dimeric lithium formate (HCOSLi)2, the PhCOS unit in 1-2 has been predicted to be predominantly ionic [6].
