Abstract Triene 22 was synthesized and converted by two different routes to the tetraaldehyde 27, the first “non-bridged” derivative of 1. An X-ray analysis of 27 reveals that the CC bond is twisted by 28.6°. Attempts to prepare 1 from 27 failed, thus far. Addition of t-butyllithium to 13, subsequent reaction with ethylene oxide and further reactions led to the highly strained tri-t-butylethylethylene 33; according to force field calculations 33 has the largest fragmentation strain of all synthesized hydrocarbons of this type.

Abstract The sterically hindered alkenes 6 and 7 , which are potential precursors for the synthesis of tetra-tert.butylethene, were prepared. Attempts at the synthesis of 5 via the thiadiazoline route failed.
