Halogen‐Imparted Reactivity in Lithium Carbenoid Mediated Homologations of Imine Surrogates: Direct Assembly of bis‐Trifluoromethyl‐β‐Diketiminates a…

2020

The selective formal insertion (homologation) of a carbon unit bridging the two trifluoroacetamidoyl chlorides (TFAICs) units is reported. The tactic is levered on a highly chemoselective homologation-metalation-acyl nucleophilic substitution sequence which precisely enables to assemble novel trifluoromethylated β-diketiminates within a single synthetic operation. Unlike previous homologations conducted with LiCH2Cl furnishing aziridines, herein we exploit the unique capability of iodomethyllithium to act contemporaneously as a C1 source (homologating effect) and metalating agent. The mechanistic rationale grounded on experimental evidences supports the hypothesized proposal and, the struct…

Ancora sulle "esplosive palatali" nelle inchieste dell'Atlante Linguistico del Mediterraneo (ALM): i punti albanesi

2021

Tra i «Problemi redazionali» emersi in fase di controllo e organizzazione dei materiali giunti dalla campagna di rilevamenti dell’Atlante Linguistico del Mediterraneo (ALM), Berruto (1971-1973) rileva la proliferazione e l’eterogeneità di alcune scelte grafemiche operate da diversi raccoglitori che, impegnati in una trascrizione più o meno puntuale delle risposte ottenute, avevano interpretato e risolto variamente alcune delle indicazioni previste nel sistema di trascrizione fonetica che accompagnava il Questionario. Particolarmente complesso era emerso il quadro relativo alla trascrizione di alcune consonanti del settore “palatale”, per le quali i grafemi (e i foni a essi corrispondenti) p…

Settore L-FIL-LET/12 - Linguistica ItalianaAmong the «Editorial problems» that emerged during the control and organization of the materials coming from the survey campaign of the Atlante Linguistico del Mediterraneo (ALM) Berruto (1971-1973) notes the proliferation and heterogeneity of some graphemic choices made by different field researchers. As they were engaged in a more or less punctual transcription of the answers obtained they had interpreted and solved differently some of the directions provided in the phonetic transcription system that accompanied the Questionnaire. The picture relating to the transcription of some consonants of the palatal sector had emerged as particularly complex since the graphemes (and the corresponding phones) foreseen in the original system (ALM 1959) were insufficient. Not even the 1971 updates meant to improve the representation of some phonetic features emerged from the investigations in the operations of Response reviewing allowed to obtain a clear homogeneous picture regarding the «plosive palatal» consonants. With regard to the phonetic trait under scrutiny I have already had the opportunity to propose a path aiming to the achievement of possible operational solutions. This has taken place in view of the planned simplification / homologation and transcoding phase from the ALM original system to the IPA one - while proceeding from the examination of the Schedoni’s current state with regard to the surveys referring to central-southern Italy Corsica and Sicily (see Matranga 2019). The scope is now to investigate the same phonetic trait as proven in the materials about the surveys carried out by Lirak Dodbiba in the ALM’s three Albanian points.
