This is nonsense, and demonstrates that you

e2 is the event that clock A and clock B' are adjacent
   tA'(e2) is meaningless.

Paul, Paul, you can't say it's meaningless. A little more consideration for the other posters, and please a little more practical intelligence: there is indeed a moment, where, for A, the event e2 exists in his frame of reference, and if A' was synchronized at the start, there will be a time, and only one time of e2 that will be written on his watch.

We can easily, if we correctly master the notion of relativistic simultaneity and the notions of relative chronotropies,
reveal what this time written on the clock A' thus synchronized during e1 will be: tA'(e1)=0.
 e2 is short for "the event that clock A and clock B' are adjacent"
 At this event, tA  = (d/v)⋅√(1−v²/c²) = 0.75 s
and clock B will simultaneously in K show tB = 0.75 s
 At this event,  tB' = d/v = 1.25 s,
and clock A' will simultaneously in K' show tA' = 1.25 s
Fortunately, we have GPS now, so we can be
absolutely sure that your gedanken bullshit
has nothing in common with real clocks,
real simultaneity or real whatever.
