CAS 1663-45-2: 1,2-Bis(difenilfosfino)etano
Descrição:
1,2-Bis(difenilfosfino)etano, comumente referido como DPPE, é um ligante bidentado amplamente utilizado em química de coordenação e catálise. Apresenta dois grupos difenilfosfino ligados a uma estrutura central de etano, o que lhe permite quelar eficazmente íons metálicos. O DPPE é caracterizado por sua capacidade de estabilizar vários metais de transição, aumentando sua reatividade em processos catalíticos, particularmente em reações de hidrogenação e acoplamento cruzado. O composto é tipicamente um sólido branco a off-white à temperatura ambiente e é solúvel em solventes orgânicos como diclorometano e tolueno. Sua estrutura contribui para suas propriedades estéricas e eletrônicas, tornando-o um ligante valioso na síntese de complexos metálicos. Além disso, o DPPE pode exibir diferentes modos de coordenação dependendo do centro metálico, influenciando a geometria e reatividade geral dos complexos resultantes. Precauções de segurança devem ser tomadas ao manusear DPPE, pois pode representar riscos à saúde se ingerido ou inalado.
