An NMR study of 2-ethyl-1-butyllithium and of 2-ethyl-1-butyllithium/lithium 2-ethyl-1-butoxide mixed aggregates
A 1H, 13C, and 6Li NMR study of 2-ethyl-1-butyllithium indicated that 2-ethyl-1-butyllithium exists only as a hexameric aggregate over the entire temperature range of 25 to - 92.1 ° C in cyclopentane. Reacting 2-ethyl-1-butyllithium with 2-ethyl-1-butanol resulted in alkyllithium/lithium alkoxide …

An NMR Study of Trimethylsilylmethyllithium Aggregates and Mixed Trimethylsilylmethyllithium/Lithium trimethylsilylmethoxide Aggregates
… with TMSM-OH in attempts to form mixed alkyllithium/lithium alkoxide aggregates. 13C NMR data for these mixtures gave inconclusive results whether or not these compounds formed, which is different from other primary alkyllithium compounds studied in the past. A study of neopentyllithium, …

An NMR Study of 2-Ethylbutyllithium/Lithium 2-Ethyl-1-butoxide Mixed Aggregates, Lithium Hydride/Lithium 2-Ethyl-1-butoxide Mixed Aggregates, n-Pentyllithium Aggregates, and n-Pentyllithium/Lithium n-Pentoxide Mixed Aggregates
… variable temperature NMR study of 2-ethylbutyllithium/lithium 2-ethyl-1-butoxide mixed aggregates formed from reacting 2-ethyl-1-butanol with 2-ethylbutyllithium in two O/Li ratios of 0.2/1 and 0.8/1. The 0.2/1 sample resulted in two 2-ethylbutyllithium/lithium 2-ethyl-1-butoxide mixed …

Development of Thermoplastic Elastomers with Improved Elastic Properties Based on Semicrystalline Block Copolymers
… to the induction period, like break up of lithium alkoxide aggregates by t-BuP4, and chain length effects. Characterization of the PB-b-PI-b-PEO and PE-b-PEP-b-PEO triblock copolymers utilizing differential scanning calorimetry and special self-nucleation (SN) techniques reveals a strong …

Molybdenum and tungsen alkylidene species for catalytic Enantio-, Z-, and E-selective olefin metathesis reactions
… a bispyrrolide or through reactions between the lithium pyrrolide and the bishexafluoro-t-butoxide. Trimethylphosphine adducts of MAP hexafluoro-t-butoxide species, Mo(NAr)(CHCMe 2Ph)(pyr)[OC(CF 3)2Me](PMe3), have been prepared. An X-ray structural study of one of these phosphine adducts was …
