“…[7][8][9][10][11][12][13] There are currently no reports of the ring-opening reactions of phosphiranes analogous to those of aziridines and oxiranes, despite evidence that such a strategy could be within reach. [14][15][16][17][18][19][20][21][22][23] The instability of phosphiranes is likely due to air sensitivity, and this has previously been noted as typical of the phosphine class in general. [24,25] It is therefore of importance to investigate and improve the air stability of the phosphirane class to ensure that any developed methodology is able to produce intermediates with long shelf lives that can be routinely employed in synthesis.…”

“…39 Attempts to prepare polymeric alkylphosphines by treating (30, R ¼ Me or Ph) with lithiophosphide reagents by inducing nucleophilic ring-opening at carbon failed, the preferred route being attack at phosphorus to form a diphosphide anion, e.g., (31), and an alkene. 40 On the other hand, the established nucleophilic ring opening of epoxides by attack of phosphide anions at carbon has received further application in the synthesis of new sulfur-containing phosphine ligands, e.g., (32), from sugars 41 and a series of modular P-O-P ligands (phosphine-phosphites and phosphine-phosphinites), e.g., (33). 42 Borane-protected lithiophosphide reagents have also been used routinely in the synthesis of the heterocycle-functionalised chiral phosphines (34), 43 (35), 44 (36), 45 and (37).…”

“…Os métodos compostos podem ser utilizados, por exemplo, na determinação de mecanismos de reações utilizando as propriedades termodinâmicas no cálculo da energia de ativação e de constantes de velocidade, [7][8][9][10][11][12][13][14] úteis em pesquisas que examinam em detalhes o mecanismo através do cálculo de constantes de velocidade para cada etapa da reação. 15,16 Outras propriedades muito estudadas são as afinidades por próton [17][18][19][20][21][22][23] e por elétron, [24][25][26][27] a acidez, 28 bem como a identificação da estrutura mais estável para um determinado isômero.…”
