Usage

General Description

DI-T-BUTYL(I-PROPYL)PHOSPHINE is a type of organophosphorus compound, which is basically an organic compound featuring phosphorus. DI-T-BUTYL(I-PROPYL)PHOSPHINE is a represented by tertiary butyl groups and an isopropyl group attached to a phosphorus atom. The molecular formula of DI-T-BUTYL(I-PROPYL)PHOSPHINE is C12H27P. It is commonly used for organic synthesis because of its reducing properties. Its handling and storage require the usual precautions applicable for handling and storing flammable and potentially toxic chemicals.

Extreme Steric Hindrance: Synthesis and Structure of the Tetra(tert-butyl)phosphonium Cation - a Case of T-Symmetry

Starting from 3P and following a series of quaternisation and ylidation steps under carefully controlled conditions, the 4P+ cation could be synthesized for the first time: 3P -> 3PCH3+ -> 3P=CH2 -> 3PCH2CH3+ -> 3P=CHCH3 -> 3PCH(CH3)2+ -> 3P=C(CH3)2 -> 4P+.All intermediates were isolated.The tetra(tert-butyl)phosphonium cation was further characterized in the form of the iodide and tetrafluoroborate by means of all spectroscopic methods available.An X-ray diffraction analysis of the BF4 salt showed a face-centered cubic lattice with a superstructure (space group F - Td5).The cation has T-symmetry as predicted by theoretical force field calculations with a tert-butyl twist of 14 deg.Due to the extreme steric hindrance, the P - C bond distances are elongated and the C-C-C angles compressed.
